base: Fix fiber compilation issue for Mac OS

Browse Source 
Mac OS has deprecated the use of ucontext and at the moment we are
using a workaround to enable it. A side-effect is that the code is
marked as _POSIX_C_SOURCE and consequently <sys/mman.h> requires the
code to be also marked as _DARWIN_C_SOURCE to include the definition
of MAP_ANONYMOUS.
