Я боюсь, что большую половину времени там на самом деле скушала
проверка, в которой используется --whatprovides.

Одна из проблем со скоростью здесь в том, что rpmquery для каждого
аргумента всегда вынимает хедер из базы Packages, и для многих файлов
этот хедер, естественно, одинаковый. То есть в цикле тупо вынимает один
и тот же хедер.
Я написал программу на Си, которая отличается от --whatprovides тем,
что работает чисто на индексе, а хедер не вынимает вообще.
Соответственно, это программа не умеет показывает, к чему файл
относится, но всё ещё умеет показывать, если файл никуда не относится.
Но оказывается, что эта программа не намного быстрее, даже не в два
раза.
$ time xargs --delimiter='\n' <$TMPDIR/out hsh-run --rooter -- ./qf-or-whatprovides-check
...

Значит, вынимание хедеров не является главным узким местом, как
я сначала думал. Где-то ещё время утекает, надо будет профилировать.
