How to package inputrc

[Jonathan Brielmaier]

Hi folks,

an annoying thing for me in a default Guix installation is the lack of
an inputrc definition[0]. So while using the shell I miss going through
my bash history via "page up"/"page down" keys.

To tackle this issue I created a simple inputrc and copied to
`/etc/inputrc`:
```
# alternate mappings for "page up" and "page down" to search the history
"\e[5~": history-search-backward
"\e[6~": history-search-forward
```

In order to achieve this more elegant I could write a simple service to
copy the file to /etc. Another option would be a small package.

I think other distros provide one in the default, basic installation:
ArchLinux[1], Debian[2] and openSUSE has even a longer one.

Are others missing that too? What do you think?

Good night
Jonathan
