gallium: auxiliary: Fix standalone Android build of u_cpu_detect (v2)
Commit 463b7d0332c5("gallium: Enable ARM NEON CPU detection.")
introduced CPU feature detection based Android cpufeatures library.
Unfortunately it also added an assumption that if PIPE_OS_ANDROID is
defined, the library is also available, which is not true for the
standalone build without using Android build system.
Fix it by defining HAS_ANDROID_CPUFEATURES in Android.mk and replacing
respective #ifdefs to use it instead.
v2:
- Add a comment explaining why the separate flag is needed (Emil).
