Fix nokogiri on arm64 alpine

[dlpierce]

The nokogori gem when used in alpine linux on the arm64 platform does not provide compatible precompiled binaries. The gcompat package allows the binaries compoiled for glibc to work.

Changes proposed in this pull request:

• Add gcompat package to the Dockerfile in the hyrax-base image

Guidance for testing, such as acceptance criteria or new user interface behaviors:

• docker-compose build is successful on an arm64 computer such as an M1 Mac

when i tried to get glibc to work in alpine linux (as part of #5314) i found that the gcompat package was not sufficient, and had to go with the more involved solution here:

hyrax/Dockerfile

if gcompat works for nokogiri, good! but i figured i’d mention it here in case it doesn’t…

i know in conversations during the tech call @no-reply mentioned possibly revisiting the decision to use Alpine Linux for everything, and if it is posing a problem for M1 development, that might be a compelling reason for doing so?

Using gcompat is nokogiri's suggested solution, but I would be happy switching away from alpine too.

[no-reply]

let's move forward with gcompat for the moment. if it's not sufficient, we can always consider a bigger change later.
