ps: add support for the args column

Implement read_cmdline() for WIN32 by storing the command line in
the same way as the applet name.

The applet name is actually used for the comm column which is
truncated to COMM_LEN.  Using this as the size of the bb_comm
array avoids the need to calculate MAX_APPLET_NAME_LEN.
