  -----------
  [compiler-rt] Destroy pthread attrs after use in tests (#114923)

The attr typically located on the stack is of an opaque pthread_attr_t
type, which may be a pointer that gets initialized by
pthread_attr_init(). Explicitly clean up the attr with
pthread_attr_destroy() to avoid a leak on such platforms to avoid
unexpected test failures with lsan enabled.

This primarily affects FreeBSD; NetBSD, musl, and glibc will seemingly
all use a full-sized pthread_attr_t.
