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. <img width="828" alt="image" src="https://github.com/hexops/mach/assets/3173176/1e29142b-0419-4459-9c8b-75d92f87f822"> Signed-off-by: Stephen Gutekanst <stephen@hexops.com>
