[Mageia-i18n] Changed strings in drakpxelinux

[Oliver Burger]

Hi there,

I fixed some strings in
https://transifex.mageia.org/projects/p/drakpxelinux/resource/drakpxelinuxpot/.

Mainly it was replacing "Mageia Linux" by "Mageia" (the distribution
is simply called Mageia, not Mageia Linux, that was some kind of
leftover from Mandriva).
In one instance there was a string containing "cooker" which has been
replaced by "Cauldron".

Please check your translations and fix them where neccessary.

Oliver
