compat-wireless: copy driver files only if present

This modifies admin-update.sh to only copy files over
from a driver target directory if files are found. This
should avoid a bunch of complaints of copying files
from directories that are just placeholders for other
folders, as happens with drivers/net/wireless/brcm80211/
which has folders a Makefile, Kconfig but no files there
itself:

	brcmfmac/
	brcmsmac/
	brcmutil/
	include
	Kconfig
	Makefile
