LU-11607 tests: replace lustre_version in mds-survey/pcc/sec

The routine get_lustre_env() is available to all Lustre test
suites and sets an environment variable for the Lustre
version of servers; MGS, MDS1, etc.

In mds-survey, sanity-sec, ost-pools,replay-single and
sanity-pcc, replace the calls to lustre_version_code()
and lustre_build_version() for all server types with
definitions from get_lustre_env().

While doing this, replace ‘lustre_version_code $SINGLEMDS’
with ‘MDS1_VERSION’.  If skip_env() is called based on a
Lustre version check, change this to skip().

Clean up around any modifications by removing calls to
return() or exit() after skip() or skip_env().
