Prevent extra newlines in CMakeLists.txt after building

PowerShell's Out-File cmdlet by default writes a newline at the end of
the file. We can prevent this either by manually trimming the whitespace
before sending the output to Out-File, or simply using the -NoNewline
parameter for Out-File.

Fixes obsproject/obs-plugintemplate#49.
