Commit 2dff6e93ca (package/readline: add upstream patch to fix crash
with invalid locale specification) fixed a regression in readline 8.2
[0], that could have been caught with a runtime test. readline is a
library, so we need an executable that exercises readline.
Since readline and bash are developped in tandem [1], it is only logical
to use bash to test readline.
Add a new runtime test for bash, that checks that we can indeed run an
interactive shell, and that an non-existing locale does not cause the
dreaded segfault. We do not use the default configuration, because it
uses a uclibc toolchain, and we want to reproduce against a glibc one.
