Fix race conditions in signal handling

Avoid several race conditions by using distinct variables for the different
signals. In particular different signals received in quick succession don't
overwrite each other any more, and odhcp6c_signal_process doesn't return true
anymore when a new SIGIO is received while another is still being processed.
