Add two skip files for running the syscalls set of tests in compat. One skips the tests failing because of Musl, the second the tests that we skip or don't build at all.
Update the README to reflect those additions and explain how to use the skip files.

v2:
- Removed mentions of COMPAT
- Reworded comment around Alpine
- Added bpf_prog02 to the musl skips after further testing

+In certain cases, you might want to skip tests that are known to be failing or are yet to be supported.
+This is done by passing a file containing the names of the tests to be skip with the option ``-S`` to +``runltp``.
+We currently provide the following skip files under ``runtest/``:
- ``syscalls_musl.skip``: Skips all tests failing on a regular Aarch64 Musl based system.
- ``syscalls_aarch64_pcuabi.skip``: Skips all tests not considered while testing plain Aarch64
- with a PCuABI kernel.
+``runltp`` does not support passing multiple skip files, however this can be circumvented by using +process substitution.
+For example, in plain Aarch64 on a Musl system with a PCuABI kernel to test all syscalls but skip all +failures unrelated to the PCuABI kernel, one could run the following command:
+.. code-block::
- ./runltp -f syscalls -S <( cat runtest/syscalls_{aarch64_pcuabi,musl}.skip )

It looks like this list misses lstat01_64. Also, what about *_16? We do not build these either.
So, I found out that for some reason I had some of the *_64 tests built for compat and in my test directory, so I didn't include them in the skip list. But they really aren't built, so they should stay in. *_16 will be added in v3.
In fact there are a few more tests in syscalls that we do not build yet because they are under testcases/kernel/security: prot_hsymlinks, dirtyc0w, dirtypipe. I guess we would need to either build them or exclude them to run the whole syscalls suite.
As we don't build them I elected to include them to the skip list.
Investigating with Beata I now understand how I missed a lot of the tests to include in the skip list: I haven't really paid attention to the command line output of runltp, only the output file listing the failed tests. As tests that are not available are not counted as failed, they don't show up in the list of failed tests, which is how I missed them.
I re-ran some tests and used the command line output to check. With the skip lists in v3 they _should_ be all accounted for, and running `syscalls` with the two skip lists results in "all tests PASS".

Thanks for testing, Best regards Téo
