repo init -m foobar.xml fails if .repo/manifest.xml exists and is broken (pointing at a missing file)

Affected Version: git master (0290cad5db0eef3b15eb976dd7a017837e36c8b7)
Environment: Linux

What steps will reproduce the problem?
1. Create a manifests repository with a.xml and b.xml
2. Run repo init a.xml
3. Delete a.xml from upstream manifests repository
4. Run repo sync
5. Run repo init -m b.xml

What is the expected output?
repo switches to b.xml

What do you see instead?
repo errors while updating the manifest.xml symlink

Please provide any additional information below.
This is caused by the symlink being broken and repo using os.path.exists 
instead of os.path.lexists to check for existance before removing the old 
symlink.

See attached patch for a fix.
