Prefix kernel and logcat logs.

We now redirect the kernel & logcat logs internally so we can prefix
them properly.

Example:

kernel: [    2.343303] Netfilter messages via NETLINK v0.30.
kernel: [    2.343780] nf_conntrack version 0.5.0 (16384 buckets, logcat: --------- beginning of /dev/log/main
logcat: I/qemu-props( 1164): connected to 'boot-properties' qemud service.
logcat: I/qemu-props( 1164): receiving..

This will make it easier to diagnose issues.
