kernel-azure: Install vmlinux with root executable permissions (#4898)

Cherry-pick of abe001946e

There was a bug where debug sources were missing from sources that were
built into vmlinux. This is because find_debuginfo, the script which
extracts debug sources, looks only at files which are executable.
Because we were installing vmlinux as 644, it was being skipped.
Therefore, change to install with permissions 744.
