Bug#1001458: lintian: tag prefer-uscan-symlink has bad name and may be wrong

[Yadd <yadd@debian.org>]

Package: lintian
Version: 2.114.0
Severity: normal

Hi,

1 - the `prefer-uscan-symlink` recommends `USCAN_SYMLINK=rename` so it
    should be named `prefer-uscan-rename`
2 - `USCAN_SYMLINK=rename` is a local parameter while `filenamemangle`
    is shared in the team. When working with a MUT, missing
    filenamemangle could break uscan (especially with GitHub where all
    files are named v<version>.tar.gz). And when working in parallel with
    different packages, uscan may overwrite a previously downloaded file
    if GitHub + same_version

That's why I think this tag shoud be removed.

Cheers,
Yadd
