Fix missing atexit in 21+ static ARM executables.
The only difference between crtbegin_static.c and crtbegin_dynamic.c
is the inclusion of the atexit implementation. Until android-21,
atexit was included in libc.a. After android-21, it's expected to
come from crtbegin. In true NDK fashion, this isn't true across all
architectures. x86 and mips always had this coming from crtbegin.
Copy the android-9 ARM CRT files to android-21 and merge the crtbegin
implementations.
We should probably take a closer look at everything going on here at
some point to make sure we don't need anything new from the bionic
sources.
Test: Improved tests/device/static-executable in the NDK, built ARM
NDK, tested with and without `--platform android-21`.
