python3Packages.awslambdaric: pin to autoconf-2.71

Without the change `python3Packages.awslambdaric` fails the build
against `autoconf-2.72` as:

    python3.11-awslambdaric> checking curl version... 7.83.1
    python3.11-awslambdaric> ./configure: line 6673: syntax error near unexpected token `;;'
    python3.11-awslambdaric> ./configure: line 6673: ` ;;'

`python3Packages.awslambdaric` embeds tarballs of external dependencies
and is a bit tricky to patch. Let's pin it to a working version.
