[libvirt PATCH 3/5] syntax-check: replace vc-list-files

[Ján Tomko]

Directly invoke git ls-tree instead of the wrapper file which also:
* checks for other versioning systems
* prepends the source directory to all output lines

Since there is no srcdir prefix in the output anymore, also drop
the extra 'sed' invocation that removes it.
