Catch exception in lib/gdbserver-support.exp:gdb_exit

Browse Source 
I see the error when I run gdb-sigterm.exp with native-gdbserver
on x86_64-linux.

In gdb-sigterm.exp, SIGTERM is sent to GDB and it exits.  However,
Dejagnu or tcl doesn't know this.

This patch is to catch the exception, but error messages are still
shown in the console and gdb.log.  In order to avoid this, we also
replace gdb_expect with expect.
