reorganize relocwrapper dependencies

[Bruno Haible]

Hi Ben,

I think it's useful to separate the object files that end up in a relocatable
program from the object files that make up the relocatable wrapper (on
non-glibc systems). Reasons:
  - The size of the wrapper should be kept small, which means no xalloc
    in particular.
  - The CPPFLAGS that the user sets for his compilations may hurt when
    applied to progreloc.c.
  - It's useless for GNU hello's libgnu.a to contain xreadlink.o and similar,
    since these functions are not used by GNU hello itself.

For this reason, AC_LIBOBJ should be avoided here. This implies the use
of different autoconf macros, and therefore the direct use of e.g. xreadlink.c
without going through module 'xreadlink'.

        * modules/relocatable-prog-wrapper: New file.
        * modules/relocatable (Depends-on): Add it. Remove all other
        dependencies except progname.
        (Files): Remove build-aux/install-reloc, lib/relocwrapper.c.
