[PATCH] utils: update-kernel-headers: Support relative path to kernel git tree

[Laurent Pinchart]

When given a relative path to the kernel git tree,
update-kernel-headers.sh fails to execute the headers_install.sh script
from the kernel sources. Fix it by turning the kernel directory into an
absolute path.
