[PATCh][Revisedx2] Fix PR55521 by switching libsanitizer from mach_overrideto mac interpose functions on darwin

[Alexander Potapenko]

Jack,

Note that MAC_INTERPOSE_FUNCTIONS is always defined in interception.h
to either 0 or 1.
I'm going to keep "#if MAC_INTERPOSE_FUNCTIONS" (adding "&&
!defined(MISSING_BLOCKS_SUPPORT)
" where appropriate) in libsanitizer.
