Fix <asm/user.h> for ARM.
This patch adds missing definitions for struct user_vfp to the ARM-specific
<asm/user.h> header. This is accessed in debuggerd to dump the state of the
VFP hardware floating-point registers in case of process crash.
NOTE: Currently, the definition has been added *manually* to the cleaned-up
header to the wrong file (<asm/page.h>). This prevents re-running the
cleanup-script!
See 94519 for a fix to correct debuggerd to include the correct header.
