Canonicalize project hooks path before use

If the top-level .repo directory is moved somewhere else (e.g. a
different drive) and replaced with a symlink, _InitHooks() will create
broken symlinks. Resolving symlinks before computing the relative path
for the symlink keeps the path within the repo tree, so the tree can
be moved anywhere.
