cmake.bbclass: use `cmake --build` to build & install
Rather than presuming `make` is the generator, use cmake's generic
`cmake --build` feature (which knows to call the appropriate generator).
Both DESTDIR and VERBOSE still behave as intended when used as
environment variables instead of make variable-arguments.
As cmake-based builds don't do any configuration with `make`
invocations, we only pass `PARALLEL_MAKE{,INST}` (via a
EXTRA_OECMAKE_BUILD variable) to the underlying build tool. Make &
ninja support the same `-j N` option (and a few others), so this does
happen to work for both.
This makes it more straight forward for others to select other cmake
generators (many folks have been reaching for `ninja` lately).
