hwdb: fix parser to work with newer pyparsing

The handling of whitespace in pyparsing is a bother. There's some
global state, and per-element state, and it's hard to get a handle on
things. With python3-pyparsing-2.4.7-10.fc36.noarch the grammar would
not match. After handling of tabs was fixed to not accept duplicate tabs,
the grammar passes.

It seems that the entry for usb:v8087p8087*
was generated incorrectly because we treated the interface line
(with two TABs) as a device line (with one TAB).
