[pve-devel] [PATCH storage] factoring out regex for vztmpl

[Lorenz Stechauner]

stores the regex definition in PVE::Storage.

One test had to be adapted because it tested obsolete code. Namely:
it expects vztmpl to only end with .tar.gz, but the new regex also
includes .tar.xz, there is nothing against allowing .tar.xz files as
vztmpl files.
