Makefile: add libssp for Windows

Recent Cygwin mingw releases require linking against libssp to avoid
undefined symbols.

See https://github.com/msys2/MINGW-packages/issues/5868 for discussion.
https://github.com/msys2/MINGW-packages/issues/5803 also contains
discussion of possibly disabling the FORTIFY_SOURCE linker flag.

Fixes: https://github.com/axboe/fio/issues/881
