strtoimax: port to platforms lacking 'long long'

VMS's pre-C99 compiler lacks 'long long', so 'configure' doesn't
check whether strtoll is declared, which causes the C file to
wrongly report an error.  Problem reported by Steven M. Schweda in:
http://lists.gnu.org/archive/html/bug-diffutils/2014-01/msg00003.html
* lib/strtoimax.c (strtoull):
Declare only if HAVE_UNSIGNED_LONG_LONG_INT.
(strtoll): Declare only if HAVE_LONG_LONG_INT.
