lua: ensure pkgconfig directory exists before installing files

The lua staging and host installation commands generate a file in
usr/lib/pkgconfig, without first making sure that this directory
exists, which causes build failures if it doesn't. This commit adjusts
those installation commands to create this directory if needed.

Fixes:

Based on investigation and initial (more complicated) fix provided by
Francois Perrad <francois.perrad@gadz.org>.
