architectures in library.properties inaccurate

[TheNitek]

library.properties states architectures=* which makes my Arduino IDE choose it over the SD lib included in the esp8266 board package.
This would not be a problem, if Sd2PinMap.h did not contain
#error Architecture or board not supported.
which breaks my build. So I guess the architectures declaration should be more specific.

I've added the definitions 9543f55

BTW I think that the SD lib provided by the ESP8266 core should have the architecture field set as well https://github.com/esp8266/Arduino/blob/7b09ae5f69f8dccb5152d128c8484ec9a18adb11/libraries/SD/library.properties#L9
I'll open an issue over there.

this fix actually produce a bug, that every one user of arudino IDE is receiving notification after IDE start that update is available for SD library, but there is nothing to update. SD library is also always under Updateable libraries. Please revert and find a different way.
