Proposed commit message

gitlab,ping_federate: make system tests pass on 9.0.0

The log input has changed file identity determination from native to
fingerprint, and the default fingerprint minimum file size is 1kiB, so make
all test inputs at least this big.

The gitlab integration did not have field mapping definitions for
log.file.fingerprint, so that is added.

Note

No changelog entry for ping_federate since there is no user-facing change here.
