buildsystem: add missing defines for CLOCK_TAI, SO_TXTIME and SCM_TXTIME 

The commit c6f2cf7c2f ("cangen: add support for SO_TXTIME") relies
on several toolchain features ("CLOCK_TAI", "SO_TXTIME", "SCM_TXTIME")
which are not present in old toolchain.

Add defines to fix compilation on older toolchains.
