[issue33455] test.test_posix.TestPosixSpawn::test_specify_environment fails with custom LD_LIBRARY_PATH

[Miro Hrončok]

New submission from Miro Hrončok :

When we build Python in Fedora, we set LD_LIBRARY_PATH environment variable so 
the testsuite is run against the currently built Python.

However a test added in ef347535f289baad22c0601e12a36b2dcd155c3a 
(test_specify_environment) spawns a process without passing the environment 
variables. This means that the new process fails with 

error while loading shared libraries: libpython3.7m.so.1.0: cannot open 
shared object file: No such file or directory

And the test fails with:

test_specify_environment (test.test_posix.TestPosixSpawn) ... 
/builddir/build/BUILD/Python-3.7.0b4/build/optimized/python: error while 
loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: 
No such file or directory
test test_posix failed

Ran 101 tests in 0.608s

1 test failed again:
test_posix
Total duration: 23 min 22 sec
Tests result: FAILURE

I believe that a fix for this is to copy os.environ, update it with {'foo': 
'bar'} and pass that copy. I'll check and send PR if it works.
