epan: Remove dependency on version_info object library

Dependending on version_info is unnecessary and forces an epan
rebuild every time the git commit id changes, which can be slow,
especially with LTO enabled, and again is unnecessary.

Printing the VCS version to the TLS debug log is a minor convenience
that doesn't justify the cost to relink epan with every commit.
