[OE-core] [PATCH] cmake.bbclass: use `cmake --build` to build & install

[Cody P Schafer]

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.

This makes it more straight forward for others to select other cmake
generators (many folks have been reaching for `ninja` lately).
