cmake.eclass: workaround S=${WORKDIR} creating builddir above ${WORKDIR}
When S=${WORKDIR}, cmake.eclass would create its build directory (if
CMAKE_USE_DIR
is unset) above WORKDIR(!) as ${WORKDIR}_build. Creating directories above
WORKDIR is not legal.
Portage has its own bug (bug #889418) in that it doesn't clean up unknown
directories
above WORKDIR in PORTAGE_TMPDIR, so combined, you get a problem where "ebuild
... clean" doesn't
actually clean things up at all, and you get very confusing issues if e.g.
changing
CC between runs.
The explicit S=WORKDIR check isn't truly needed but it makes explicit our
intent here.

Closes: https://bugs.gentoo.org/889420
