Allow sdk_sandbox to read files/directory in /data/local/tmp

Browse source 
The /data/local/tmp directory is used by the CTS tests infrastructure to
store various data, like the list of tests to include/exclude after
failures
http://cs/android-internal/tools/tradefederation/core/test_framework/com/android/tradefed/testtype/AndroidJUnitTest.java;l=333-347;rcl=bbd3902197b7de1a99aef4c22db8e14e4dbf1157

Without this CL, CTS modules that attempt to re-execute failures will
get a '[INSTRUMENTATION_CRASH|SYSTEM_UNDER_TEST_CRASHED]' error.

Test results before/after this CL:
Before: http://ab/I04600010115474754
After: http://ab/I65000010115426482
Note the absence of "Module error" in the second case
