Add maximum inspection size for RAR archives

Finch showed a significant difference in inspection time when enabling
content inspection for RAR archives (http://shortn/_64qaXWf78L). I
expect this is because RARs archives tend to be very large, so
unpacking the archive takes a lot of time. This CL has the RAR
analyzer fall back to the old behavior for large (> 50MB) archives.
