configure: check if issetugid is declared

Browse source 
GNU/kFreeBSD has issetugid in libc (for legacy apps?), but doesn't
declare it anywhere, causing gcc to error out with
-Werror=implicit-function-declaration.  Use AC_CHECK_DECL in addition to
AC_CHECK_FUNC so we disable this code instead of failing to build it.
