Then use Lrs().absolute_filename()
and LrsNash().absolute_filename() (see #31296).

This makes these parts of the Sage library fully functional even when not being run from within sage-env (which sets PATH). To test this on a system without system lrslib installed, after sage -i lrslib:

$ venv/bin/python3 -c 'from sage.all import *; print(polytopes.hypercube(3).volume(engine="lrs"))'
$ venv/bin/python3 -c 'from sage.all import *; A = matrix([[1, -1], [-1, 1]]); B = matrix([[-1, 1], [1, -1]]); matching_pennies = NormalFormGame([A, B]); print(matching_pennies.obtain_nash(algorithm="lrs"))'

Depends on #31296
