Subject: [PATCH] domain.te & kernel.te: allow kernel to write
nativetest_data_file
to workaround some VTS VtsKernelLtp failures introduced by
change on vfs_iter_write here:
https://android.googlesource.com/kernel/hikey-linaro/+/abbb65899aecfc97bda64b6816d1e501754cfe1f%5E%21/#F3
for discussion please check threads here:
https://www.mail-archive.com/seandroid-list@tycho.nsa.gov/msg03348.html
Sandeep suggest to re-order the events in that thread,
that should be the right solution,
this change is only a tempory workaround before that change.
Test: manually with -m VtsKernelLtp -t VtsKernelLtp#fs.fs_fill_64bit
