Subject: [PATCH] This patch allows telegram-cli to build on Apple Silicon by
 leveraging the sysconfdir macro from autoconf

1. Add SYSCONFDIR define which is set to the autoconf provided @sysconfdir@
2. Remove the FreeBSD #ifdef around tgl_set_rsa_key, and replace
   with #ifdef SYSCONFDIR around tgl_set_rsa_key, to use SYSCONFDIR for location of server.pub
