ldc2-1.18.0.ebuild: eninja fails in installing phase with ACCESS DENIED

[Boris Carvajal]

It seems that the command eninja -C "${BUILD_DIR}" install doesn't respect the sandbox mode and tries to use the root fs.
A quick fix is adding DESTDIR="${D}" to the cmd:
DESTDIR="${D}" eninja -C "${BUILD_DIR}" install

Furthermore I think the best solution is to keep using cmake-utils_src_{make,install},
delete -G Ninja from mycmakeargs and set either:
CMAKE_MAKEFILE_GENERATOR="ninja" at the start or EAPI=7.
With the new eapi ninja is the default generator for cmake.

Ah thanks, I'm not really up to date with build ebuild writing. I'll update the ebuild with your patch.
