canonicalize, canonicalize-lgpl: Straighten dependencies

[Bruno Haible]

The modules canonicalize, canonicalize-lgpl don't need to depend on
'malloc-posix', 'free-posix' any more, since they don't call malloc() or free()
directly (as they now delegate their memory handling to the module
'scratch_buffer').

OTOH, since they include <unistd.h>, they need to depend on module 'unistd'.

        canonicalize, canonicalize-lgpl: Straighten dependencies.
        * modules/canonicalize-lgpl (Depends-on): Remove free-posix,
        malloc-posix. Add unistd.
        * modules/canonicalize (Depends-on): Remove free-posix, xalloc.
        Add unistd.
