Ed Maste 7cafe89f9c sanitizers: Improve FreeBSD ASLR detection 
The kern.elf64.aslr.pie_enable and kern.elf32.aslr.pie_enable sysctls
control the default setting for PIE binary address randomization, but
it is possible to enable or disable ASLR on a per-process basis.  Use
procctl(2) to query whether ASLR is enabled.

(Note that with ASLR enabled but sysctl kern.elf64.aslr.pie_enable=0
a PIE binary will in effect have randomization disabled, and be
functional with msan.  This is not intended as as a user-facing control
though.  The user can use proccontrol(1) to disable aslr for the
process.)
