build_image: fix /usr/lib/debug handling with dev images

Browse Source 
gdb only looks in /usr/lib/debug, not anywhere in /usr/local.  So
unpack the C library stuff into the common /usr/local/usr/lib/debug
and symlink /usr/lib/debug to the /usr/local tree.  This way gdb can
find all these things automatically.

BUG=None
TEST=run gdb on board and see it find .debug files automatically
