[gold][patch] Add .debug_types to list of known gdb sections

[Cary Coutant]

The --strip-debug-gdb option currently strips the .debug_types
section, but shouldn't. This trivial patch adds it to the list of
sections to keep with this option. (I also added it, commented out, to
the list of sections to keep for --strip-debug-lines.)

OK?
