[lldb/testsuite] XFail TestBuiltinTrap.py not only on linux

[friss]

Summary

TestBuiltinTrap fail on darwin embedded because the __builin_trap
builtin doesn't get any line info attached to it by clang when
building for arm64.

The test was already XFailed for linux arm(64), I presume for the same
reasons. This patch just XFails it independently of the platform.

I don't currently have arm hardware to try this on, but it sounds like a safe assumption.
