std: correct getcontext for Android bionic libc
I have updated Felix's ZigAndroidTemplate to work with the latest
version of Zig and we are exploring adding Android support to Mach engine.
`std.c.getcontext` is _referenced_ but not _used_, and Android's bionic libc
does not implement `getcontext`. `std.os.linux.getcontext` also cannot be
used with bionic libc, so it seems prudent to just disable this extern for now.
This may not be the perfect long-term fix, but I have a golden rebuttal to that:
before I was unable to compile Zig applications for Android, and now I can.
