tests: Skip daemon-conf test if dir exceeds UNIX_PATH_MAX

Browse Source 
The max path length for unix sockets is pretty small (108, see man 7 unix).
If 'make check' is run from a directory that exceeds this, one of the tests
will fail, and in such a way that requires manually editting the test to
determine why.

There are certainly other ways to handle this, but I've chosen just to skip
the offending test if we will exceed the length limitation.

v2: Drop bashism, use test infrastructure to warn and skip
