Replace utxrm(8) by utx(8).

Browse Source 
At first, I added a utility called utxrm(8) to remove stale entries from
the user accounting database. It seems there are cases in which we need
to perform different operations on the database as well. Simply rename
utxrm(8) to utx(8) and place the old code under the "rm" command.

In addition to "rm", this tool supports "boot" and "shutdown", which are
going to be used by an rc-script which I am going to commit separately.

The first argument to

Write a boot time record to the user accounting database.
This option should typically only be used by

Write a shutdown time record to the user accounting database.
This option should typically only be used by
.Xr rc 8 .
.It Cm rm
Remove stale sessions from the user accounting

.Ar identifier .
Stale sessions can occur if a login service exits prematurely or fails
