docs: add --pid=host to ebpf command line.

Browse Source 
A lot of the `iovisor/bcc` tools take a pid as a command line option and using
`--pid=host` allows you to use `$(pgrep foo)`

You probably want to run with
`docker run -it -v /sys/kernel/debug:/sys/kernel/debug --privileged mobylinux/ebpf:tag sh` for
`docker run -it -v /sys/kernel/debug:/sys/kernel/debug --privileged --pid=host mobylinux/ebpf:tag sh` for
interactive use as some things use debugfs. You need at least `CAP_SYS_ADMIN` to do anything.
There are examples in `bcc/examples` that should generally just work, I have tried several of
the Lua ones.
