largefile, year2038: simplify if Autoconf 2.72
* m4/largefile.m4 (gl_SET_LARGEFILE_SOURCE)
(_AC_SYS_LARGEFILE_MACRO_VALUE):
* m4/year2038.m4 (gl_YEAR2038_EARLY, gl_YEAR2038, gl_YEAR2038_BODY):
Adjust to Autoconf 2.72, which should contain the Gnulib
patches in this area and so should not need to be overridden.
