Don't audit linkerconfig in dumpstate

dumpstate creates an error log from CTS test because dumpstate does not
have access to linkerconfig directory. As df doesn't need to scan
linkerconfig directory, do not audit this directory in dumpstate
to get attributes.

Bug: 148760417
Test: m -j passed
Test: No sepolicy error from correspoding test
