[patch] OptionalPackage : WifiFirmwareScriptData

[mmadia]

This optional package is for people who build their own images & have wifi hardware that requires install-wifi-firmwares.sh & have no active network connection. This package is not to be added to default images, due to restrictions with their copyright/licenses.

For now, the user is required to add install-wifi-firmwares.sh and the respective drivers in their UserBuildConfig. Some more patches need to come in until all of the wifi drivers are ready to be added to the default image. At that point, the optional packages Wifi-iprowifi2200+fw and Wifi-ipw2100+fw can be removed.

To note, currently install-wifi-firmwares.sh will remove & recreate finddir B_COMMON_TEMP_DIRECTORY/wifi-firmwares/ This in turn deletes the wl_apsta-3.130.20.0.o needed by function CutAndInstallBroadcomFirmware()

The new patch accounts for this.

To note, currently the files are downloaded in the directory that jam is run. If/When #5110's patch is added (either in part or in whole), DownloadFile will then download to $(HAIKU_DOWNLOAD_DIR).

In light of hrev35617, this needs more updating than I originally expected. Will get to it later today or tomorrow.
