Avoid implicit declaration memset in have_fpos_pos.c probe #68

Otherwise, the probe result changes with compilers which do not support implicit function declarations, a language feature that was removed from C in 1999.

Thank you @fweimer-rh for this pull request. You are quite correct on the need to be consistent with modern C.

Much appreciated!
