Auto merge of #1280 - semarie:openbsd-glob_t, r=gnzlbg

openbsd: glob_t recently changed to conform posix (use size_t)

on openbsd, upcoming stable version have changed glob_t definition to follow posix definition (using `size_t` instead of `int` on some fields)

the change preserves bitrig definition
