CR_SYSTEM_GL_PATH should not require trailing slash on Linux hosts

[cendaaro]

Judging by line 23 of the attached log file, VirtualBox expects the CR_SYSTEM_GL_PATH to have a trailing slash (the correct location of the file is /opt/VirtualGL/fakelib/64/libGL.so.1, and CR_SYSTEM_GL_PATH=/opt/VirtualGL/fakelib/64). This is generally inconsistent with environment variable convention in Linux (see $PATH for example).

Lines 157-159 of trunk/src/VBox/GuestHost/OpenGL/spu_loader/glloader.py confuse me slightly, as it seems to imply that Linux builds should *not* have a trailing slash appended. The strange thing is that this code hasn't changed since VirtualBox v3.x when I didn't have this problem. Perhaps the VirtualBox build environment has changed so that "linux" is now defined, or perhaps I am barking up the wrong tree altogether...?

Feedback appreciated.

Obsolete, there were a lot of changes in that area and VirtualBox 6.1 dropped Chromium altogether.
