MSYS .gitattributes typo: Wrong line ending normalization under Windows

Typo in https://github.com/mosra/magnum-integration/blob/master/package/msys/.gitattributes

magnum/PKGBUILD text eof=lf
PKGBUILD text eof=lf

There is no attribute named eof, they're supposed to be eol attributes.
Because of this typo, Git on Windows wrongly normalizes the PKGBUILD files to CRLF line endings.
Last time I reported this typo in the other magnum repos I didn't know this repo existed 😄

Ah damn, sorry! 😅 I thought I checked for the same problem everywhere, but apparently not.

Will push a fix tomorrow.
