Revert SO_???TIMEO-based STARTTLS timeout handling.

This reverts commits 47c05b10018f5ec7493e4bd9f521aaa18d96f1e2
and 72ce8bce8dd655b6aefa33d0a74e883dad5202b5, the code isn't portable,
for instance, Solaris does not support SO_RCVTIMEO/SO_SNDTIMEO.
These socket-level options are known, but Solaris returns EAFNOSUPPORT.

Reported by Jonathan Buschmann.
