fix(lnd-detection): Lookup lnd using explicit output specifiers

`ps x -o pid,command` rather than `ps lx`

The default ps-node lookup is via ps lx, which includes:

  -l Display information associated with the following keywords:
    uid, pid, ppid, flags, cpu, pri, nice, vsz=SZ, rss, wchan,
    state=S, paddr=ADDR, tty, time, and command=CMD.

On mac, the `ps l` output can be misaligned, e.g. when some VSZ field is
longer than expected.

Many of these fields are unnecessary because we're looking up by name only,
so we can lookup using only the command fields of ps.
