command(): don't start using procfs_getargv() instead of kvm_getargv()
...
just because the latter returned a NULL - that may normally happen,
when the process is, for example, a kernel thread
procfs_getargv(): if the name is brackened in '(' and ')', just
return NULL immediately - the code in command() will DTRT
and the output will be same for procfs- and kvm- based lookup
in all cases

When using the procfs for extracting process information, extract
...
also process start time, process arguments and session leadership status.
The procfs fallback is also used when kvm_openfiles() completely fails
(e.g. when /dev/mem is not readable).
Solves PR 7772, though the final implementation is different.

Minor fixes:
...
1. Use statfs() to verify that /proc is a procfs.
2. Add -K option to disable /proc-based method.
3. Make warnings less verbose, but still accurate.

Added experimental fallback /proc-based lookup. Warnings are printed when the
...
fallback method is used, as the results could be untrustworthy if an
intruder is present. It is highly likely that NetBSD-1.5 will have
an improved kvm interface for reading process information, at which
point this code can be garbage-collected. Also added a word to the
man page -x option description while I was here.

- change setgid kmem programs (that lend themselves to this) so setegid(getgid())
...
and the top, and then set the effective gid back to kmem around the call to
kvm_openfiles(). this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
kvm_openfiles() to fully revoke priviledges.
- some KNF
- use err(3) over fprintf(3) in some places
