Thomas Petazzoni 3ae900bcf9 package/gdb: remove BR2_PACKAGE_GDB_TOPLEVEL
This option was needed to build versions of GDB < 10.x. As we just
dropped support for GDB 9.x, this logic can now be removed.

The special case to configure just gdbserver was only valid for gdb<10,
but was guarded by !GDB_TOPLEVEL (which was equivalent to gdb<10).
GDB_TOPLEVEL is now always true, so we can't hit that special case
anymore.
