LU-10254 tests: fix racer version checks

Fix the checks for enabling DOM, PFL, and FLR tests in file_create.sh.
The $LCTL variable was unset in the test script, so the version check
was failing.

Instead of doing the version check inside file_create.sh do it in the
Lustre-specific racer.sh test script, where other version checks live.
This enables PFL and FLR testing by default, but leaves DOM tests off.
