doc: Install gpg and gpgv man pages under the correct name.

* doc/mkdefsinc.c (main): Add double include guard.  Set variable
gpgtwohack. Define macros gpgname and gpgvname.
* doc/gpg.texi: Remove macro definition for gpgname.  Use Texinfo var
gpgtwohack to prepare the man pages.  Use @gpgname everywhere.
* doc/gpgv.texi: Likewise.
* doc/Makefile.am (myman_pages): Remove gpg2.1 and gpgv2.1 but add
them depending on USE_GPG2_HACK.
