[Msan] Make the pthread_getattr_np_deadlock.cc test Linux-specific

#ifdef FreeBSD

The point of the test is to have the first memory allocation in a thread to happen inside pthread_getattr_np.

It ends up with segfault without the pthread_attr_init() call on FreeBSD. Should we just XFAIL this test?

[eugenis]

XFAIL sounds good, or just move it to Linux.

[kutuzov.viktor.84]

Updated.

LGTM

Looks like patch was not committed.
