imv, ipc: improve error checking for ipc creation.
Since this isn't essential functionality, it's ok to simply not provide
it. In cases where XDG_RUNTIME_DIR was empty (but not unset) or set to a
directory where the user didn't have write permissions, socket creation
would fail and lead to segmentation faults in imv, due to the return
value of imv_ipc_create() not being checked.
