build: Solaris needs __EXTENSIONS__ instead of _GNU_SOURCE 

Fix meson build on Solaris by using __EXTENSIONS__ where Linux & other
platforms use _GNU_SOURCE.  Without this the build fails due to missing
prototypes for functions like strdup & getopt not defined in the C99
standard.  (In autoconf, this was handled by AC_USE_SYSTEM_EXTENSIONS.)
