Fabricio VoznikaandgVisor bot ed38782b23 Remove omitempty for fields than can be 0 
Some fields can have a legitimate value of 0 and that was
causing the field to be omitted from the output, giving the
impression that it hasn't been set.

Ayush RanjanandgVisor bot 6fdeba8d78 Add support for /prod/[pid]/cmdline and /proc/[pid]/environ to trace procfs.

Ayush RanjanandgVisor bot cf039a68d8 Add trace procfs command. 
`runsc trace procfs` should dump a lot of relevant procfs information about
all the processes in the container. Falco will consume this.

For now the only procfs entry that the procfs dump returns is /proc/[pid]/exe.
Will incrementally add support for the remaining in separate changes.
