pick up all *.vty in EXTRA_DIST

(Same as osmo-bsc I47c9011b5e0e2886d221e34e6aa281d1dd0495c7)

*.vty tests are picked up by the Makefile.am by means of a wildcard --
they are run when they are there. So when you forget to add it to
EXTRA_DIST, it will be run in your local build tree, but it will be
silently omitted from a distribution tar, and nothing will complain
about it gone missing.

Instead, also use a *.vty wildcard in EXTRA_DIST. So any *.vty test
added to the git source will both be run *and* included in distribution
tars implicitly.

So far, test_neighbor_ident.vty was missing from the distribution.
