Without this fix, c-ares fails to build, with this symptom:
/usr/include/sys/unistd.h:218:14: error: expected ‘;’ before ‘void’

Previously, tty::restore sets the console mode to a predetermined
console mode that is widely common for many non-cygwin console apps.
So, if a non-cygwin app that is started from cygwin process changes
the console mode and executes cygwin sub-process, the console mode
is changed to the predetermined mode rather than being restored the
original mode that is set by the non-cygwin app.
With this patch, the console mode is stored when a cygwin process is
started from non-cygwin app, then tty::restore restores the previous
console mode that is used by the previous non-cygwin app when the
cygwin app exits.

The HEAD commit is recorded by update-patches.sh in
msys2-runtime.commit, and the contents of that file are passed to the
--with-msys2-runtime-commit configure argument, so that uname -r shows
the msys2-runtime commit hash rather than the commit hash of the
upstream Cygwin tag.
Fixes#5223
