Fix the changehat_wrapper regression test

Browse Source 
The capabilities tests where failing in the changehat_wrapper test.  This was because
they could not the changehat_wrapper sub executable, which trying to exec a binary
in the tmpdir.

Specifically if the test was for syscall_ptrace.  It would generate a profile with
a hat for ^syscall_ptrace and attempt to execute ./syscall_ptrace.  However this
was failing in some situations, including when trying to debug from the tmpdir,
as the syscall_XXX binary is no longer local.

Instead use the fully qualified path for the hat name, and the exec path.
