Makefile installs desktop files with executable permissions

[notpeelz]

Describe the bug
When installing syncplay, the desktop files get chmod-ed to 755. On my system (Arch Linux), syncplay is the only package that deploys desktop files with executable permissions.

/usr/share/applications:

Expected behavior
Permissions of 644, not 755. Desktop files aren't supposed to be executable.

Version and platform:

• OS: Arch Linux
• Syncplay version: Syncplay 1.7.1

I've traced back the specific code that changes those permissions to a commit with several changes almost 10 years ago. There was no explanation why .desktop files needed executable permissions in it.

I see no reason not to change them to follow what all the other .desktop files do.
