is_nss_browser process name check is brittle and doesn't include Microsoft Edge

[erik-anderson]

Problem Description

In #2681, a check for the process name was added to check for "chrome", "chromium", and "firefox". As far as I can tell, this is unlikely to cover other Chromium-based browsers like Microsoft Edge ("msedge").

Proposed Resolution

Add other Chromium-based browsers that are available on Linux.

Other context

I was looking at this code because the Microsoft Edge team received a report from a customer that a crash happens in Microsoft Edge when they move to 0.23.0-0.1ubuntu1 from 0.20.0-3ubuntu0.1~esm1. That crash looks like heap corruption and the customer doesn't see the issue in Google Chrome, so I decided to see if there were any clear browser detection code paths. I don't have any smoking gun yet on where the heap corruption is happening, unfortunately.

Since #2681 was added after that release, I don't think it's pertinent to the customer-reported problem, but it would presumably cause Chrome vs. Edge behavior differences in 0.24.0, so I'm proactively filing this issue.

We would be happy to detect Edge. If msedge is indeed reliable, feel free to open a pull request adding this to the list.

The only reported crash of Firefox (as NSS browser) that is still present in 0.23.0, that I am aware of, is #2419. This is fixed in master and may be worth trying...

Also note that you may always set slots_per_card = 1 (the default for NSS browsers) via opensc.conf without any changes to the code.
