pimd: don't break with missing SO_BINDTODEVICE

Browse Source 
This effectively a partial revert of commit 61ea395...
"pimd: Bind pim sockets to interface they are associated with"

Note this isn't really a proper fix, it just clears the build breakage
on BSD without improving the usage of multiple sockets.
