* use struct path_cxt to read from /procfs
* add --sysroot to redirect lsfd to alternative location (necessary
for regression tests)
* merge collect_procs() into collect()

* make COMMAND and NAME truncated by default (to keep output on terminal readable)
* add --notruncate to disable the default behaviour
