Add binary cataloger for Nginx built from source

[blang9238]

What would you like to be added:
Many organizations build Nginx (and other technologies) from source but when generating an SBOM using Syft on an image with Nginx built from source, no artifacts are included in the SBOM.

Why is this needed:
Vulnerability matches do not occur for packages built from source like Nginx.

Additional context:
Example make command in Dockerfile:

module=/tmp/nginx-upload-module-2.3.0 && \
    make && \
    make install
