fix include to find SIOCGSTAMP with latest kernel

In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
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 pulled so we get a build failure.

canlogserver.c: In function 'main':
canlogserver.c:404:21: error: 'SIOCGSTAMP' undeclared (first use in this function); did you mean 'SIOCGRARP'?
     if (ioctl(s[i], SIOCGSTAMP, &tv) < 0)
                     ^~~~~~~~~~
                     SIOCGRARP
canlogserver.c:404:21: note: each undeclared identifier is reported only once for each function it appears in
