Isolate dracut logs inside the generated initramfs to its own folder

[LaszloGombos]

Inside initramfs move the following text files out of the root of /lib/dracut/ folder. These files are not essential for booting.

• lib/dracut/modules.txt
• lib/dracut/build-parameter.txt
• lib/dracut/dracut-*

Some ideas where to move them:

• /lib/dracut/log/
• /lib/dracut/share/
