Testsuite fails on alpha due to incorrect filename for libc.so.6.1

[glaubitz]

Explain what happens

The testsuite fails on alpha as it assumes that the name of the shared C library is always libc.so.6:

=========================== short test summary info ============================
ERROR test/pytest/test_beiboot.py - OSError: libc.so.6: cannot open shared object file: No such file or directory
ERROR test/pytest/test_bridge.py - OSError: libc.so.6: cannot open shared object file: No such file or directory
ERROR test/pytest/test_pcp.py - OSError: libc.so.6: cannot open shared object file: No such file or directory
ERROR test/pytest/test_peer.py - OSError: libc.so.6: cannot open shared object file: No such file or directory
ERROR test/pytest/test_transport.py - OSError: libc.so.6: cannot open shared object file: No such file or directory
!!!!!!!!!!!!!!!!!!! Interrupted: 5 errors during collection !!!!!!!!!!!!!!!!!!!!
================== 1 deselected, 1 warning, 5 errors in 3.96s ==================

However, on alpha and ia64, it's actually libc.so.6.1.

Dang, there are no porter boxes for alpha nor ia64, so I suppose I need to fix this blindly.

This first needs to be fixed in ferny, then synced over, and then do the same fallback in

src/client/cockpit-client:libc6 = ctypes.cdll.LoadLibrary('libc.so.6')
src/cockpit/transports.py:libc6 = ctypes.cdll.LoadLibrary('libc.so.6')

I sent allisonkarlitskaya/ferny#32 . Once that lands, I'll fix it in cockpit.
