app-emulation/vmware-modules: add support to kernel 4.15-rc2

Patch inspired to https://github.com/mkubecek/vmware-host-modules/commit/562121d7bc06
but I prefer to leave the sources as close as possible to the original ones.

The changes are due to kernel commits b9eaf18722221ef8b2bd6a67240ebe668622152a
and e99e88a9d2b067465adaa9c111ada99a041bef9a
