[patch] Use in `file-truename' in `flymake-create-temp-inplace'

[Arne Jørgensen]

If the temp-name in `flymake-create-temp-inplace' is going through
symlinks reported errors might not get catched if they contain the
expanded file name.

Wrapping temp-name in `file-truename' will make the file names
consistent in the error reports and in flymake.

Kind regards,
Arne
