Subject: [ci skip] [lldb] Ensure rbbt has loaded the globals

rb_backtrace relies on the existend of RUBY_T_MASK. This is set up by
the global loading code in lldb_init()

rb_backtrace does not call lldb_init previously, and therefore would
only work if called after another lldb function that _did_ load the
globals.
