android_gdbserver - fix warning about missing shared library symbols

The warning was:
	warning: Could not load shared library symbols for 4 libraries,
	e.g. /system/bin/linker.  Use the "info sharedlibrary" command to
	see the complete listing.

Fixed by grabbing all of those libraries along with libc.so.
