[PATCH v3 2/6] meson: check for getpagesize before using it

It is deprecated and removed in SUS v3 / POSIX 2001, so various systems may not include it. Solaris, in particular, carefully refrains from defining it except inside of a maze of `#ifdef` to make sure you have kept your nose clean and only used it in code that *targets* SUS v2 or earlier.

config.mak.uname defines this automatically, though only for QNX.

v2: add this only for !windows

v3: rebase now that it is a dict
