LU-11782 tests: add version check to conf-sanity 117

conf-sanity test 117 was added to check error returns from
read_param().  This test will fail when run with servers
with Lustre version less than 2.12.0 and, thus, should be
skipped for all Lustre servers earlier than 2.12.0.

Fixes: 6ca2425ccf6b ("LU-11198 utils: propagate errors for read_param")
Test-Parameters: trivial
Test-Parameters: serverversion=2.10.8 serverdistro=el7.6 env=ONLY=117 testlist=conf-sanity
