rs.te: Remove dontaudit statements

These dontaudit rules were in place to suppress SELinux denials due to
file descriptor leakage. The file descriptor leakage has been fixed, so
these rules are no longer necessary. Delete.

Fixes: 120983106
Test: cts-tradefed run cts-dev -m CtsRenderscriptTestCases
