[PATCH] gdb: constify remote files_info

[Mike Frysinger <vapier@gentoo.org>]

The sim and m32r remote targets declare a local "file" variable and only
assign const strings to it before passing it to a printf() func.  So add
const markings to avoid gcc warnings like:
gdb/remote-sim.c: In function 'gdbsim_files_info':
gdb/remote-sim.c:789: warning: initialization discards qualifiers
	from pointer target type

	* remote-m32r-sdi.c (m32r_files_info): Add const to local "file" var.
	* remote-sim.c (gdbsim_files_info): Likewise.
