gdb: fix shellcheck warnings SC2034 (unused variable) in gdbarch.sh

shellcheck reports:

    In gdbarch.sh line 139:
                    fallbackdefault="0"
                    ^-------------^ SC2034: fallbackdefault appears unused. Verify use (or export if used externally).

Indeed, the `fallbackdefault` variable appears to be unused, remove the
code that sets it.

gdb/ChangeLog:

* gdbarch.sh: Remove code that sets fallbackdefault.
