samba: Run populate-volatile.sh update in postinst

samba-common installs a volatiles configuration file but had not been
calling populate-volatile.sh to apply the configuration. This causes
samba installation to fail on a running target due to missing
directories.

Call "populate-volatile.sh update" in samba-common's postinst which
creates the required directories and enables samba to work.
