bcc: move from linux-kernels packages to normal packages

Browse Source 
bcc doesn't really need kernel itself, it just cares about module path.

It's actually better to use /run/booted-system/kernel-modules/lib/modules
for two reasons:
 - no need to rebuild bcc for each new kernel
 - can use a newer bcc with a booted kernel that doesn't match the current
   system
