commonlib/fsp.h: include sys/types.h for ssize_t

This file reportedly didn't compile on SUSE Linux with gcc 4.3.4:

[...]
    >     HOSTCC     cbfstool/fsp_relocate.o
    > In file included from coreboot/src/commonlib/fsp_relocate.c:18:
    > coreboot/src/commonlib/include/commonlib/fsp.h:26: error:
    > expected '=', ',', ';', 'asm' or '__attribute__' before
    > 'fsp_component_relocate'
    [...]

According to POSIX-2008[1], sys/types.h defines ssize_t, so include it.
    This should not break coreboot code (as opposed to utils code), as we
    have a sys/types.h in src/include.
