fix: works when ran through a symlink

[EDM115]

closes #849

I'll let you bump the version and create the executables
Successfully tested on Windows :

I only tried the built windows executable, but this shouldn't affect builds for other distros.
Also my knowledge in Perl is really the bare minimum so there could be a better way to write it or maybe some imports are duplicated. All I know is that it works :)

also I didn't modified Unix/cloc but tbh I don't really know how this repo works 😅

[AlDanial]

Impressive. Thanks for making the effort to figure this out. I have one minor request: please move the line with
my $exec_path = abs_path($0); inside the if test for $ON_WINDOWS.

[EDM115]

done 👍

Tip

If anyone still have issues, here's the built artifact for 2.02 :
cloc_#850_2.02.zip

Don't trust me ? Wanna build it yourself ?
git clone https://github.com/AlDanial/cloc.git && cd cloc
(Needs to have Perl installed, like Strawberry Perl on Windows)
cpan -i Digest::MD5 && cpan -i Regexp::Common && cpan -i Algorithm::Diff && cpan -i PAR::Packer && cpan -if Win32::LongPath (last one may fail to execute one test on latests SP versions)
pp -M Win32::LongPath -M Encode::Unicode -M Digest::MD5 -c -x -o cloc.exe cloc
Copy-paste the .exe into %LOCALAPPDATA%\Microsoft\WinGet\Packages\AlDanial.Cloc_Microsoft.Winget.Source_8wekyb3d8bbwe\
