Regenerate two Makefile.in files to update Copyright headers

Regenerate two Makefile.in files to update Copyright headers

commit 1d506c26d9772bcd84e1a7b3a8c8c5bc602dbf61
Update copyright year range in header of all files managed by GDB
updated gnulib/Makefile.am but didn't regenerate gnulib/Makefile.in
also sim/Makefile.in was updated, but the Copyright hunks/years
were off. The first hunk comes from automake 1.15.1 header-vars.am
and so should have 2017 as last year, the second hunk does come from
sim/Makefile.am and so should have 2024 as last year.

	* gnulib/Makefile.in: Regenerate.
	* sim/Makefile.in: Likewise.
