package/skeleton: also handle merged /usr in the staging

Browse Source 
When the target uses a merged /usr setup, gdbserver will only report
paths in /lib to the remote gdb, which in turn will only look for
libraries in staging/lib and never in staging/usr/lib.

So. the merged (or non-merged) /usr setup must be replicated in the
staging.

The best solution where to do so is in the skeleton package, since it
is guaranteed to come before any package that installs things in the
staging, and even before the (internal or external) toolchain as well.
