Fix import paths after vendored pip update

To reproduce:
find src/fetchcode/vcs/pip -type f -name '*.py'i \
    -exec sed -i 's/from\ pip._/from\ fetchcode.vcs.pip._/g' {} + \
    -exec sed -i 's/import\ pip._/import\ fetchcode.vcs.pip._/g' {} + \
    -exec sed -i 's/"pip._/"fetchcode.vcs.pip._/g' {} +

This is very similiar to what was done in:
