gpgconf: Improve registry dumping.

* common/w32-reg.c (read_w32_reg_string): Add arg r_hklm_fallback and
change all callers.
(show_configs): Indicate whether the HKLM fallback was used.
* tools/gpgconf.c (show_other_registry_entries): Fix the Outlook Addin
Registry key.  Indicate whether the HKLM fallback was used.
--

Note that this is  backport from 2.2.  The new support there for
REG_DWORD needs to be implemented in libgpg-error, though.
