[PATCH v3 1/6] gdb/testsuite: check that "info shared" and "info linker-namespaces" before running don't crash

[Simon Marchi <simon.marchi@efficios.com>]

This patch is new in v3.

While writing my solib_ops C++ification series, I broke this, and it
didn't seem to be caught by the testsuite.  Add a test for those.

The exact message for "info linker-namespaces" varies depending on the
solib_ops of the target architecture (whether ops->num_active_namespaces
is nullptr or not).  For now, just accept any message (a crash will
still be caught).  A later patch in this series will make the message
consistent and update this test.
