remove assumption of lp chroot extension

[dann frazier]

[Impact]
s-l-c is unable to consume LP chroots. Launchpad appears to have changed the extension of stored chroots, presumably in https://git.launchpad.net/launchpad/commit/?id=3d107db183c22f6653412291bf1d66c3a2edf984

[Test Case]
Current bionic (0.14):

$ sudo sbuild-launchpad-chroot create -n bionic-amd64-sbuild -s bionic -a amd64
[bionic-amd64-sbuild] Creating config
Reading package lists... Done
Building dependency tree
Reading state information... Done
qemu-user-static is already the newest version (1:2.11+dfsg-1ubuntu7.21).
The following package was automatically installed and is no longer required:
  grub-pc-bin
Use 'sudo apt autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 96 not upgraded.
[bionic-amd64-sbuild] Initial download
[bionic-amd64-sbuild] Processing config
[bionic-amd64-sbuild] Remote tarball isn't .tar.bz2.
[bionic-amd64-sbuild] Done creating

While it says "Done creating" - it actual has only created the config, not the chroot.

[Regression Risk]
A fix for this is simple, and has shipped since Eoan:

Thanks for doing this Dannf.

This bug was fixed in the package sbuild-launchpad-chroot - 0.14ubuntu0.18.04.1

---------------
sbuild-launchpad-chroot (0.14ubuntu0.18.04.1) bionic; urgency=medium

  * Don't enforce .tar.bz2 suffix for the tarball, just use what Launchpad
    gives us; tar will handle it just fine. (LP: #1858458)
