package/hwdata: install to staging

hwdata provides a .pc file, which other packages can look up to find the
location where hwdata files are, and use them at build time.

This is the case for the upcoming libdisplay-info package, which
requires the hwdata's PNP IDs at build time.

However, installing the .pc file is not enough. Indeed, meson (which
libdisplay-info uses) will look for the corresponding data files in
datadir, which it locates relative to the sysroot, which is our staging.

So, we also need to install the hwdata files in staging.
