Update user permission check for --help

[itstrueitstrueitsrealitsreal]

PR Description:

Fixes #2553
This pull request updates the script to allow the --help command to run without requiring root privileges. The modification ensures that users can access the help message without elevated permissions, addressing the issue reported in #2553.
I chose not to change the occurrence of this warning when running archinstall --help in the code, as it would help users without root permissions to access the logfile more easily.

Not enough permission to place log file at {log_file}, creating it in {fallback_log_file} instead

Changes Made:

• Updated the root check logic to bypass if --help or -h is present in the arguments.
• Shifted define_arguments() to come before the check for root permissions so the entire list of commands are displayed.

Tests and Checks

• I have tested the code and confirmed that archinstall --help displays the help message without requiring root privileges.
