ptrace: move SIGTRAP on exec(2) logic to ptrace_event()

Browse Source 
Move SIGTRAP on exec(2) logic from tracehook_report_exec() to
ptrace_event().  This is part of changes to make ptrace_event()
smarter and handle ptrace event related details in one place.

This doesn't introduce any behavior change.
