Linux Install Script Desktop File

[ibrummel]

As of ver1.8.9, available on the arduino.cc website, the installer script is generating a desktop file where the Exec=/path/to/arduino/executable line is not being quoted, leading to invalid desktop file errors when installed.

This requires a simple fix of generating the .desktop file such that:
Exec=/path/to/arduino/executable
is instead:
Exec="/path/to/arduino/executable"
