bug#26967: alpine: provide system-wide config

[ng0]

Without this patch, alpine silently(?) complains until a
$HOME/.pinerc exists:

Global config 
"/gnu/store/57k152vswq14m2ialxacmnrkar17vcan-alpine-2.21/lib/pine.conf" is 
default
Personal config "/home/user/.pinerc" is default
Exceptions config not set on cmdline
  checking for default "/home/user/.pinercex" in pinerc dir
    no, there is no exceptions config
    
      Global config:     
/gnu/store/57k152vswq14m2ialxacmnrkar17vcan-alpine-2.21/lib/pine.conf
        Personal config:   /home/user/.pinerc
          Exceptions config: <none>
            Fixed config:      
/gnu/store/57k152vswq14m2ialxacmnrkar17vcan-alpine-2.21/lib/pine.conf.fixed

With this patch, we profive these missing files.
The way they are created is copied from slackware and seems to be
the recommended way of providing them, as no such file exists in
the distribution of alpine.
