fs: support RENAME_NOREPLACE for local filesystems
This is trivial to do:
- add flags argument to foo_rename()
- check if flags doesn't have any other than RENAME_NOREPLACE
- assign foo_rename() to .rename2 instead of .rename
Filesystems converted:
affs, bfs, exofs, ext2, hfs, hfsplus, jffs2, jfs, logfs, minix, msdos,
nilfs2, omfs, reiserfs, sysvfs, ubifs, udf, ufs, vfat.
