Fixes https://github.com/inducer/grudge/pull/248/

x-ref: https://github.com/inducer/grudge/pull/247#discussion_r843447075

* Bump tolerance for test_mass_mat_trig in test_grudge_sym_old

* Set tolerances in test_mass_trig (for old sym code) equal to ones in new-style tests

This ensures that the symbolic stuff remains tested until we remove it.

The issue is that the same expression (dx0/dr0) appears in
both a user provided expression and the discretization
metrics and the code generator gets confused.
