[Libguestfs] [PATCH 2/2] customize: allow editing symlinked files



Resolve also symlinks when checking whether a path passed to --edit is a
file: the file editing code supports symlinks anyway (properly changes
the target file, instead of overwrite the symlink with a real file), so
it is safe to allow this operation in customize/builder.
