Start writing up some basic feature tests for procstat
These tests query a running process for information related to the -b, -c, -e, and -f flags; the -f testcase is largely stubbed out, pending additional work to determine a good, deterministic descriptor. Core file test support is coming soon--it requires a bit more effort due to the fact that: - coredumps can be disabled (kern.coredump=0). - corefiles can be put in different directories than the current directory, or be named something other than `<prog>.core` (`kern.corefile`).
