stop morph from using fakeroot and sudo

Instead, assume the whole build will be run, by the user, under
fakeroot or sudo (the latter for system image builds). This allows
us to run all non-system-image-build tests without root access
at all.

We now always create the cache directory, if missing, even if
we're running as root.

We no longer run ldconfig if ld.so.conf is missing. It is missing
during our tests, but is (now) created by fhs-dirs for real builds.
