locktest: remove manual declaration of errno

locktest.c has already #included <errno.h>, so remove the unneeded
(and in some cases, incorrect) manual declaration of errno as an
integer.  Some C libraries use a macro to provide thread-safety for
errno, so it's incorrect to try to provide a manual declaration.
