Well, I had expected that there might be some defaults set somewhere
in a text file (or as comments) …

… but perhaps not. I notice that the patch is for else clauses,
which could indicate fallback PATHs when nothing else is found.

And these patches do look like they're in the code:

 $ strings /tmp/lightdm/usr/sbin/lightdm | grep /bin:
 /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
 /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
 PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
 PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
 $ 

Cheers,
David.
