RAR5 reader: fix bad shift-left operations.

This commit fixes some undefined shift-left operations on types that do
not support such a big shift. Those invalid shift operations were
triggering on invalid files produced by fuzzing.

The commit also contains two unit tests that ensure such problems won't
arise in the future.

Fixes OSSFuzz cases #14490 and #14491.
