t0027: check the eol conversion warnings

Depending on the file content, eol parameters and .gitattributes
"git add" may give a warning when the eol of a file will change when
the file is checked out again.

There are 2 different warnings, either "CRLF will be replaced..." or
"LF will be replaced...".  Let t0027 check for these warnings by
adding new parameters to create_file_in_repo(), which tells what
warnings are expected.

When a file has eol=lf or eol=crlf in .gitattributes, it is handled
as text and should be normalized.  Add tests for these cases that
were not covered.
