Subject: [PATCH] remove deprecated notice
Upstream: https://github.com/longld/peda/pull/176
From GDB 12.1+, `set logging on|off` is deprecated, and a notice is
given. See
<https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob_plain;f=gdb/NEWS;hb=gdb-12.1-release>.
This patch fixes the issue for the newer gdb versions.
