pylama: Use %s instead of %t

Although using %t to lint changes was desirable, many pylama checks use
surrounding paths and file contents (e.g. C0103 module name, E0402
relative import beyond top, etc.)  The more such errors I find during
testing, the less %t seems like a good idea.  Switch to %s.

Also set `lint_file` to 1 and mark Pylama as a file linter in the docs.
