ANDROID: fuse: Skip canonical path logic if ENOSYS

Browse Source 
Not all FUSE servers have implemented canonical_path such as virtiofs.
This patch makes it so they go through the same logic as other
filesystems that don't have canonical path implemented.

Bug: 330136711
Test: ./cts-tradefed run commandAndExit cts -m CtsIncidentHostTestCases -t com.android.server.cts.ErrorsTest#testTombstone
