Allow user to skip updating VideoCore libraries

Users who are running non-raspbian distributions, especially on other architectures like arm64, may already have videocore libraries and applications compiled for arm64. These will get overwritten unless updating the VideoCore libraries is skipped. This implements a SKIP_VCLIBS option to allow that step to be skipped, which may be used alongside the SKIP_SDK option. This is also referred to in a suggestion for a SKIP_USERLAND option here: Hexxeh#221 (comment) Signed-off-by: Satadru Pramanik <[email protected]>
