build linux-firmware script cannot expend star sign if firmware name is a glob string
For example: brcmfmac firmware has "brcm/brcmfmac*-sdio.*.bin". and this firmware path/name should be expanded again.
L58 cannot expand wildcard again.
So linux-firmware deb didn't contain all firmware that driver required.
