[PATCH] 9053193: Remove the ext3/ext4 special case from supportsFileAttributeView

The implementation of FileStore.supportsFileAttributeView for linux still incorrectly assumes that ext3 and ext4 don't support user_xattr and skips the filesystem probe using fgetxattr. On recent kernels this prevents any application from using extended user attributes without special configuration (fstypes.properties) or reflection.
This patch removes this assumption and let's the implementation continue on with properly probing the file system for support.
