[PATCH] usbutils: avoid dependency on bash

[Paul Eggleton]

By virtue of having #!/bin/bash, the usb-devices script declared that it
requires bash, however manual examinasion, checkbashisms and tests with
dash and busybox show that it doesn't contain any bashisms, so change
the script's header and remove the RDEPENDS on bash.

Is the update-usbids ash/dash safe as well nowadays?

Manual examination shows no bashisms, checkbashisms reports nothing, and it 
works fine with ash here.

Cheers,

Since I also made a spelling mistake in the original commit message let me 
make a v2 also noting that this has been checked as well.

Cheers,
