uapi headers: include <sys/dtrace_types> as needed

This is needed for _LITTLE_ENDIAN and _BIG_ENDIAN.

Add a new internals test to identify this class of failure: add a
tag 'uninstalled' which is disabled in the installed tree to prevent it
from being executed as part of the installed testsuite (since it is not
particularly useful outside the installed set, and making it work in
both places would be complicated and annoying).
