[PATCH v2 1/1] git-clean.txt: clarify ignore pattern files

[Denton Liu <liu.denton@gmail.com>]

In the git-clean documentation, -x and -e documented .gitignore,
$GIT_DIR/info/excludes but neglected to mention the file pointed to by
core.excludesFile.

Remove specific list of files and, instead, reference gitignore(5)
documentation so that information is consolidated and the git-clean
documentation is more precise.
