Apply snap-preseed optimizations after seeding snaps

Browse Source 
The snap-preseed command can do a number of things during the build
that are currently performed at first boot (apparmor profiles, systemd
unit generation, etc).  This patch adds a call to reset the seeding and
apply these optimizations when adding a seeded snap.  As a prerequisite
to calling snap-preseed we need to make /dev/mem available as well as
mounts from the host to perform this work, so those are also added here.
