patch: propagate eolmode down to patchfile
The old code mapped the value of eolmode ('strict', 'crlf' or 'lf') to
eol (None, '\r\n' or '\n') at the entry point in internalpatch. The
value of eol was then used directly as the desired EOL in patchfile.
We now delay the mapping and let patchfile do it instead. This allows
for more complicated behavior where it does not make sense to map
eolmode directly to the target EOLs.
