Fix CONFLICTS entries in archivers, astro, audio

Fix conflicts entries based on a script that searches for duplicate
files installed by several ports.

Some patters seem to make ports conflict with themselves, but this is
actually not the case due to the check-*-conflicts logic implemented
in bsd.port.mk, which excludes self-conflicts.

PHP based ports have been ignored in this commit as requested by the
committers currently working on the php-8.1 import.

*/*: Remove redundant '-[0-9]*' from CONFLICTS

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

Many CONFLICTS definitions used patterns like "bash-[0-9]*" to filter
for the bash package in any version. But that pattern is functionally
identical with just "bash".

- Add port lang/squirrel
- Register conflicts with archivers/squsq

Squirrel is a high level imperative/OO programming language, designed
to be a powerful scripting tool that fits in the size, memory bandwidth,
and real-time requirements of applications like games. However Squirrel
offers a wide range of features like dynamic typing, delegation, classes
& inheritance, higher order functions, generators, coroutines, tail
recursion, exception handling, automatic memory management, weak
references, etc.

Squirrel is inspired by languages like Python, Javascript and especially
Lua. The API is very similar and the table code is based on the Lua one.
