[PATCH] test/pasta_options: Ignore failures on shell 'exit'

[Stefano Brivio <sbrivio@redhat.com>]

On shell 'exit' commands, running shells from pasta, we might get:

  Cannot set tty process group (No such process)

as some TTY devices might be unaccessible. This is harmless, but
after commit "pasta: propagate exit code from child command", we'll
get test failures there, at least with dash.

Ignore those explicitly with a ugly workaround: we can't simply do
something like:

	exit || :

because the failure is reported by the shell itself once it exits,
regardless of the command evaluation.

This is already applied, I needed to unblock tests. Posting anyway
for reviews.
