Subject: kernel: Fix depmod for multilib

Using populate_sysroot for this data was a nice idea but flawed as it
doesn't work in multilib builds. Instead we can use PKGDATA_DIR since
this is consistent over multilib builds. It also turns out to be
slightly neater code too. Hopefully this resolves the problem once and
for all.
