gpg: Re-add checking of config file permissions.

Browse source 
* g10/gpg.c (main): Re-add permission checking of the user config
file.  Re-add code to check against the SE-Linux secured file list.
(get_default_configname): Remove unused func.
* configure.ac (SAFE_VERSION, SAFE_VERSION_DOT)
(SAFE_VERSION_DASH): Remove.

Die to the switch to the new option parser, the permissions were not
anymore checked.  This patch fixes this.  Note that there there is no
checking for the global config file because that file is not expected
to be user modifiable.

This patch also adds checking against the list of SE-linux secured
files.  However, like in the old code the checking does not work in
practise because the to be checked files are added to the the list
only after option parsing.  Tested using temporary debug code.

The SAFE_VERSION macros were used for RISC OS, which is not anymore
supported, and only in the now removed get_default_configname.  There
purpose was that a RISC OS could use a modified config.h here.
