protocol-native: Disable srbchannel for setups without SCM_CREDENTIALS

srbchannel needs fd passing. Otherwise we get the following error
for systems without SCM_CREDENTIALS support:

    Code should not be reached at pulsecore/pstream-util.c:95,
    function pa_pstream_send_tagstruct_with_fds(). Aborting.

[[ The root cause is that we define HAVE_CREDS only if
SCM_CREDENTIALS is defined, but SCM_CREDENTIALS is a Linux-specific
symbol. Thus HAVE_CREDS is always disabled on Solaris.

And since pulse couples the non-portable creds passing support
with the portable fd passing one, through _35_ places where
HAVE_CREDS is used, a real fix needs a PA redesign -- assuming that
latency on Solaris is something people care about. ]]
