LU-11607 tests: replace version/fstype in sanity-dom/quota

The routine get_lustre_env() is available to all Lustre test
suites and sets an environment variable for the file system
type for MDS1 and OST1 and sets variables for the Lustre
version of servers.

In sanity-dom and sanity-quota, replace the calls to
facet_fstype() and lustre_version_code() for all server
types with definitions in get_lustre_env().

While doing this, replace 'facet_fstype $SINGLEMDS' and
'lustre_version_code $SINGLEMDS' with $mds1_FSTYPE
and $MDS1_VERSION, respectively.

Clean up around any modifications by removing calls to
return after skip() or skip_env() and convert spaces
to tabs.
