[PATCH] nitb/vty: Add test for E1 input keep-alive

[Jacob Erlbeck]

This test checks, whether the configuration of e1_line keepalive
works. It does not check, whether keep-alive is correctly implemented
by the drivers.

If the e1_line keepalive command is not provided by the libosmo-abis,
this test will be skipped.
