cmd: Expand the storage space for qualifiers.

When parsing a command, after the first '/' we store the characters away
in quals. The command itself can be MAXSTRING in bytes, but the quals was
limited to MAX_PATH. This is incorrect, as you can provide very long
qualifiers as well. Expand the space to allow the maximum size possible.
