lib/Makefile.inc: Correct filename to master_header_pointer.c

Builds are failing sporadically with:

src/lib/master_header_pointer.c:5:10: fatal error: fmap_config.h: No such file or directory
    5 | #include <fmap_config.h>
      |          ^~~~~~~~~~~~~~~

Correct the filename in the Makefile from header_pointer.c to
master_header_pointer.c so that there's a dependency from
master_header_pointer.c to fmap_config.h.
