tests: Add wraps for __xstat/__fxstat variants of stat/fstat

__xstat and __fxstat variants of stat/fstat are invoked under
chromium chroot. For all existing tests it is sufficient for
stat/fstat to "do nothing, return 0", so new wraps do just that.

Test which needs __xstat: linux_mtd lifecycle.

Tests which need __fxstat:
read_chip_test_success
read_chip_with_dummyflasher_test_success
write_chip_test_success
write_chip_with_dummyflasher_test_success

Without this patch tests above fail under chromium chroot.

BUG=b:181803212
TEST=running tests on three different environments,
1) stat64/fstat64 (ninja tests in upstream tree)
2) stat64/fstat64 (ninja tests in chromium tree)
2) __xstat64/__fxstat64 (emerge with tests in chromium tree)
