dev-qt/qtwebengine: add check-reqs for disk space and memory usage

For now, assumes:
- RAM/memory: 2GB per job for GCC, 1.5GB per job for Clang
- Disk (build): 7GB
- Disk (installed): 150MB

(Also moves pkg_preinst to the end of the ebuild to reflect
phase execution order, as per devmanual.)

Closes: https://bugs.gentoo.org/570534
Thanks-to: Ionen Wolkens <ionen <AT> gentoo.org>
