The futex_numa_mpol test requires libnuma, which is not available on
all platforms. When the test is not built, the run.sh script fails
because it unconditionally tries to execute the test binary.

Check for the futex_numa_mpol executable before running it. If the
binary is not present, print a skip message and continue.

This allows the test suite to run successfully on platforms that do
not have libnuma and therefore do not build the futex_numa_mpol
test.
