gdb/hurd: pass memory_tagged as false to find_memory_region_ftype

I tried building GDB on GNU/Hurd, and ran into this error:

  CXX    gnu-nat.o
gnu-nat.c: In member function ‘virtual int gnu_nat_target::find_memory_regions(find_memory_region_ftype, void*)’:

This is because in this commit:

  commit 68cffbbd4406b4efe1aa6e18460b1d7ca02549f1
  Date:   Thu Mar 31 11:42:35 2022 +0100

      [AArch64] MTE corefile support

Added a new argument to find_memory_region_ftype, but did not pass it to
the function in gnu-nat.c.  Fix this by passing memory_tagged as false.

As Luis pointed out, similar bugs may also appear on FreeBSD and NetBSD,
and I have reproduced them on both systems.  This patch fixes them
incidentally.

Tested by rebuilding on GNU/Hurd, FreeBSD/amd64 and NetBSD/amd64.
