FreeBSD x86: Remove fallback for detecting signal trampolines by address.
A few FreeBSD releases did not include the page holding the signal
code in core dumps. As a workaround, a sysctl was used to fetch the
default location of the signal code instead. The youngest affected
FreeBSD release is 10.1 released in November 2014 and EOLed in
December 2016. The fallback only works for native processes and would
require a separate unwinder once the FreeBSD arches are converted to
use tramp_frame for signal frames.
