Linux Additions: do not try to remove kernel modules on clean-up.
bugref:3809: Linux installer maintenance

When we uninstall Linux Additions it is normally not possible to unload all
kernel modules. However we generally succeeded in removing vboxsf. When
upgrading this resulted in an error message when trying to load the new
version and further meant that shared folder functionality was guaranteed
not to be available until the next guest restart. This change drops the
unload attempt.

36## @todo This file duplicates a lot of script with vboxdrv.sh. When making
37# changes please try to reduce differences between the two wherever possible.
38
39# Testing:
40# * Should fail if the configuration file is missing or missing INSTALL_DIR or
41# INSTALL_VER entries.
42# * vboxadd user and vboxsf groups should be created if they do not exist - test
43# by removing them before installing.
44# * Shared folders can be mounted and auto-mounts accessible to vboxsf group,
45# including on recent Fedoras with SELinux.
46# * Setting INSTALL_NO_MODULE_BUILDS inhibits modules and module automatic
47# rebuild script creation; otherwise modules, user, group, rebuild script,
48# udev rule and shared folder mount helper should be created/set up.
49# * Setting INSTALL_NO_MODULE_BUILDS inhibits module load and unload on start
50# and stop.
51# * Uninstalling the Additions and re-installing them does not trigger warnings.
