patch: drop eol normalization fast-path for 'lf' and 'crlf'

With eolmode set to 'lf' or 'crlf' we avoided the hunk duplication and
normalization by reading the input patch in text mode. Dropping this
optimization simplifies code expectations for a small overhead.

The change in test-mq-eol comes from a tolerance to CRLF instead of LF for last
lines without newlines being broken by this revision. This tolerance was only
partially supported and will be added again in a better way.
