lib/oe/patch: handle creating patches for CRLF sources

Using devtool to patch CRLF based sources creates patch files which have
mixed end of lines : LF for headers and CRLF for source context and
modified lines.

Python open(..., newline=None) (default for newline arg)does detect
end-of-line in this mixed file but only outputs LF EOL data. This
result in patch files that does not apply on the original sources.

Switching to open(..., newline='') allows to detect end-of-line but keep
the original end-of-line intact. This generate correct patches for CRLF
based sources.

Fixes [YOCTO #15285]
