Non-Ubuntu Distro Accessibility and Formatting

[thebitstick]

• Fixes for Surface Go - Touchscreen #251 not working on distro without update-rc.d (non-Ubuntu)
• Newline formatting is not default on Fedora/RHEL, so adding -e beautifies output
• Checks for Ubuntu before even asking user to install Ubuntu packages

The .deb packages work on other apt-based distributions though, and not
just on ubuntu. By checking for ubuntu, you wouldn't detect Mint,
Debian or Elementary OS I think (definitly not Debian, idk if the
others change the ID).

I actually made a pull request that does similar (if not the same, lol)
changes (#538), which just checks for the package manager (i.e. if
apt / dpkg is installed .deb packages are used, and if pacman is
installed the arch packages will work).

Feel free to rip those changes out of my PR in order to simplify
merging this if you want.

Oh! I'm sorry about that! I'll include the changes from b4ddc70 in this PR!
( off note but thank you for the fedora packaging! )

Nice!

Oh! I'm sorry about that!

No worries! But actually, one thing I still want to suggest:

In #538 I reorgnized the script a bit so it installs libwacom right
before installing the kernel. That allowed me to use only one if / else
check for the package manager, instead of two (that need to be kept in
sync). Maybe thats something you should add too, to have less
duplicated code?

Another note, because I just read that in the planned changelog:
Fedora 31 won't contain the yum wrapper anymore, so checking for that
will fail. The script should check for dnf instead (even if someone
is crazy enough to use these packages on CentOS / RHEL, they are
switching to dnf too - RHEL already did iirc.)

Sorry for nagging xD

Alright it should be ready to merge!
