[Libguestfs] [PATCH 3/3] customize: add globbing for --delete

[Pino Toscano]

Support globbing in paths passed to --delete, telling glob to not
return directories with leading slash.

This re-adds back globbing for --delete in virt-sysprep, which was
available before the integration with common code from virt-customize.

 Delete a file from the guest.  Or delete a directory (and all its
 contents, recursively).
