gnu: cmake, cmake-minimal: Use cmake-build-system.

This allows removing the bundled LibUV in a subsequent commit.  This commit
alone makes no functional changes apart from the build system adjustments.

* gnu/packages/cmake.scm (%common-build-phases, %common-disabled-tests): New
variables.
(cmake-bootstrap)[arguments]: Refactor to use the shared phases and tests.
(cmake-minimal)[build-system]: Change to CMAKE-BUILD-SYSTEM.
[arguments]: Adjust accordingly.
(cmake)[arguments]: Likewise.
