cmd/compile: only sort methods/interfaces during export for -d=unifiedquirks

Browse Source 
These sorts are only important for 'toolstash -cmp' testing of unified
IR against -G=0 mode, but they were added before I added
-d=unifiedquirks to allow altering small "don't care" output details
like this.

This CL should help mitigate issues with #44195 until package
objectpath is updated and deployed.
