test: Remove testonly=True from test toolchain implementations (#1327)
Upcoming Bazel versions enforce testonly-ness through toolchain lookup,
so when `:current_py_cc_headers` depends on (via toolchain lookup) a
`py_cc_toolchain(testonly=True)` target, an error occurs.
To fix, just remove testonly=True from the toolchain implementation.
Fixes #1324
