Basic: normalise android triples when loading modules

[compnerd]

The android API level can be ignored when loading the module. The API
level controls the NDK APIs which are available and is equivalent to the
SDK version for Darwin. This allows us to keep the API level in the
triple which future versions of Android's toolchain does.

Replace this paragraph with a description of your changes and rationale. Provide links to external references/discussions if appropriate.

Resolves SR-NNNN.

Seems that the test should be limited to when the Android stdlib has been built. I don't know how that can be transformed into a lit requirement, thought.

I mean, I could do // REQUIRES: OS=android. But, I'm trying to be clever and create the Swift.swiftmodule manually just to make sure that we build and test with different triples. This seems to work locally, I wonder why it doesn't work here.
