ninja fix CASSANDRA-19002: Set gcgs in HintsMaker to Integer.MAX_VALUE

HintsMaker was creating hint files which ttl'ed after 10 days which started to fail the tests.
By setting it explicitly to Integer.MAX_VALUE, newly generated hint files will expire in cca 68 years.

Branches 3.0 to trunk introduce the fix to HintsMaker. Branches 5.0 and trunk contain regenerated hint files as well.
