    initrd: Support to specify a PFS label in 'vfs.root.realroot'
    
    The 'vfs.root.realroot' syntax previously didn't support to specify a
    PFS label for a HAMMER/HAMMER2 filesystem on an encrypted partition.
    There was a hack to work around this limitation by naming the mapped
    device with 'd' in the end (e.g., use 'rootd' rather than 'root'), so
    the kernel would auto mount the '@ROOT' PFS from it.
    
    However, it was impossible to work around the limitation when the target
    PFS uses a custom label, e.g., '@ROOT.20260616'.
    
    This commit fixes the limitation by extending the rcmount_{crypt,tcplay}
    scripts to support to directly specify the PFS label in
    'vfs.root.realroot'.
    
    Update and improve the initrd(7) man page accordingly.
