progname tweak

[Bruno Haible]

Ralf reminded us that we should be able to build libraries which don't
cause name clashes.

This patch makes it possible to #define set_program_name to an alias.

        Make it possible to #define set_program_name to an alias.
        * lib/progname.c: Don't undefine set_program_name; instead, undefine
        ENABLE_RELOCATABLE early.
