python check-interpreter.mk issue with egg.mk

[David Brownlee <abs%absd.org@localhost>]

Looks like check-interpreter.mk is broken on egg.mk using packages -
example from x11/arandr below

> Bootstrap dependency digest>=20211023: found digest-20220214
WARNING: lang/python/egg.mk is deprecated; use lang/python/wheel.mk instead.
[...]

ERROR: [check-interpreter.mk] The interpreter "python" of

ERROR: [check-interpreter.mk] The interpreter "python" of
"/var/obj/pkg/x11/arandr/work/.destdir/usr/pkg/bin/unxrandr" does not

Could someone take a look?

Obviously the goal is to convert all packages to wheel.mk instead of
egg.mk, but with ~1900/3500 packages still using egg.mk its a little
bit of an ask to just convert them all to avoid this issue :-p
