Since linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
(2019-04-19) the asm-generic/sockios.h header no longer defines
SIOCGSTAMP. Instead it provides only SIOCGSTAMP_OLD.
The linux/sockios.h header now defines SIOCGSTAMP using either
SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. This linux only
header file is not included so we get a build failure.
