        share/mk/bsd.prog.mk: revision 1.322

Add PAXCTL_FLAG rules for MKSANITIZER

Add per-program rules to disable ASLR for ASan, TSan and MSan in all
sanitized programs. This flag is not needed for other supported sanitizers.

Without this change, sanitized init(8) dies early on startup.
Approach originally suggested by <joerg>
