add sys/types.h to configure check for videodev.h

[Adrian Harvey]

videodev.h, requires sys/types.h to be included if sys/time.h is
otherwise it does not compile correctly (ulong undefined) and the
configure check fails even though it is present. 

(tests done on on Fedora Core 3 x86_64 edition)

Patch is against latest CVS, and I have included the autoconf generated
changes to configure as well.
