Adjust the all.gyp:All target for iOS

Adjust the all.gyp:All target for iOS

The initial iOS version was over-ambitious, and doesn't yet build. To
get the build working, this:
- only builds base:base on iOS, not base:*, and
- disables warnings-as-errors in third-party code for iOS, since
  at least NSS and ICU have warnings for iOS.

This also adds nss.gyp to the iOS build, now that its gyp support
has landed

I'm having trouble parsing this gyp file.  Is the below "dependencies" section
only run on OS=ios?  What part of the syntax is causing that?

This is gyp-ese for if/else.

'conditions': [
  [<condition>, { if-true stuff }, { if-false stuff} ],
]

Where the whole |, { if-false }| part is optional.

Agreed it's hard to read but it'll be gone again in a week, maybe two, so I'm
not too worried.

Oh, I see.  So this is the else-clause, OS==ios.  Cool.
