Revert "vpath usage - simplify to bare minimum to make gustavo happy"

This reverts commit 2037474dc0fd2b360452f2a15abcbe533b57ca37.

This causes the wayland_shm engine to seg fault immediately at
startup when attempting to create shm buffers.

Please make sure when committing changes to the wayland_shm engine to
test on intel, exynos, and at least one platform without dmabuf
capabilities - or using the EVAS_WAYLAND_SHM_DISABLE_DMABUF env var
to disable dmabuf on intel or exynos.

Anyone without the time or hardware to fully test changes to wayland_shm
can submit a patch to phabricator and assign it to me so I can fully
test it before landing.
