LU-13149 tests: change sanityn 103 facet value

LU-13149 tests: change sanityn 103 facet value

The facet name input to lustre_version_code() in sanityn
test 103 should be 'ost1' not a variable '$ost1'.  Let's
replace this call with the $OST1_VERSION variable.

Fixes: 2548cb9e32bfca ("LU-11670 osc: glimpse - search for active lock")
Test-Parameters: trivial
Test-Parameters: serverversion=2.10.8 serverdistro=el7.6 env=ONLY=103 testlist=sanityn
