[PATCH] git-download: Fix 'git-predicate' to use absolute paths.

[Christopher Baines]

git ls-files will return paths relative to the repository directory. This
commit prepends the repository directory to those paths when calling lstat,
such that 'git-predicate' works if the current working directory is not the
repository directory.

* guix/git-download.scm (git-predicate): Prepend repository directory to the
  file path when calling lstat.
