Subject: [PATCH] fix: GCC 15 compatibility -- missing includes and CFLAGS

- Drop -Wpedantic (triggers new pedantic errors in GCC 15)
- Add -Wno-implicit-function-declaration to CFLAGS
- Add nisrom_finders.c to all Makefile targets that use nislib_shtools.c
  (nislib_shtools.c calls check_ivt() which is defined in nisrom_finders.c)
- Add missing #include "nisrom_finders.h" in nislib_shtools.c, nisrom.c,
  nisrom_finders.c (GCC 15 rejects implicit function declarations in C99)
- Fix md5/md5.c: use local include "md5.h" instead of system <md5.h>
