612368b59e Improve decoding of Android's PR_SET_VMA prctl 
Before:

  prctl(0x53564d41 /* PR_??? */, 0, 0x7f8ab53000, 4096,
        "atexit handlers") = 0

After:

  prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, 0x7fa8cbd000, 4096,
        "atexit handlers") = 0

* prctl.c (SYS_FUNC(prctl)) [__ANDROID__]: Do not define PR_SET_VMA.
* Hard-code PR_SET_VMA_ANON_NAME, the only current sub-option.
* xlat/prctl_options.in: Add PR_SET_VMA.
