[component] error while loading shared libraries with python

[chittaja536]

Description

I ran the command : bazel build //hw:verilator

I see that it complains about not being able to find libpython3.7m.so.1.0, however, /usr/bin/python3.7.0/lib is set in the LDB_LIBRARY_PATH variable.

Bazel cuts environment variables when building, so only python's default paths will be looked at. I don't know whether or not yours is a default, I've had this problem with python modules before (#18689).

Would you mind trying with LDB_LIBRARY_PATH added to rules/nonhermetic.bzl?

Fixed by #19476 perhaps?
