pack: fakechroot: Honor $LD_LIBRARY_PATH.
Until now, when using the "fakechroot" engine, $LD_LIBRARY_PATH would
always be ignored. However, it's useful in some cases to allow users to
specify LD_LIBRARY_PATH, so honor it.
* gnu/packages/aux-files/run-in-namespace.c (concat_paths): New function.
(exec_with_loader): Concatenante $LD_LIBRARY_PATH to the relocated
AUDIT_LIBRARY_PATH.
