Always transmit SIGPROF back to the inferior. 

Summary:
SIGPROF is used for profiling processes (with google-perftools for
instance), which results in the inferior receiving a SIGPROF from the
kernel every few milliseconds. Instead of stopping the debugging session
and notifying the user of this, we should just pass the signal and keep
running.

This follows the behavior we have in UnixSignals.cpp.

Test Plan: Run LLDB on linux with a binary using google-perftools, see that execution gets interrupted all the time because we receive SIGPROF. Apply the patch, everything works fine.
