configure.ac: Add `strdup` to AC_CHECK_FUNCS.
* configure.ac: Add `strdup` to AC_CHECK_FUNCS since we are using it and
the whole point of libgroff's `strsave()` was to get along without it.
But `strdup` has been standardized in POSIX for 20 years (SUSv3,
POSIX:2001) and is on its way into ISO standard C (N2354) and C++
(P2391R0) as well.
