tests: fix build & disable testcommands

The perils of having tests, the test wasn't tested thoroughly enough...
Fixup various automake problems, and then disable it since it depends on
configure parameters in its current version.

For 0.99.24 we can ship a static copy of vtysh_cmd.c and have it
reenabled.
