[Buildroot] [git commit] download/git: fix transform-name

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=54785851eeb775720aac8a0b6b423fda26ac8f27
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When a package contains a relative symlink which first component is '..'
(thus pointing one directory higher), for example package 'meh' contains
this symlink:

    foo/bar -> ../buz

then it would be stored as 'meh-version./buz' because of the
transform-name pattern replacement.

Fix it to only match the leading './'.
