test: suppress misc warning messages

* Remove leftover `check_PYTHON` call. The PYTHON is already checked
with check_python3() earlier.

* In checking existence of mydef_boot, check its bin folder. The module
path (modules/mydef_boot) may exist even without submodule checkout.

* Add cast to suppress the "%lld" printf when the actual type may be
"long" instead of "long long".

* Add -w in Makefile_f77.mtest to suppress all warnings since gfortran
always gives warnings despite -fallow-argument-mismatch.
