bison: rely on bison's %require to check a version requirement

See https://lists.gnu.org/archive/html/bug-gnulib/2020-05/msg00021.html.

* m4/bison.m4 (gl_PROG_BISON): Let bison itself decide if it it recent
enough of not.
So far it is the only know Yacc tool that supports '%require'.
Other yaccs will actually even choke on seeing the -o option after the
input file name.
* m4/parse-datetime.m4: Simplify gl_PROG_BISON invocation.
