rtla: Use str_has_prefix() for option prefix check

Browse Source 
The argument parsing code in timerlat_main() and osnoise_main() uses
strncmp() with a length of 1 to check if the first argument starts
with a dash, indicating an option flag was passed.

Replace this pattern with str_has_prefix() for consistency with the
rest of the codebase. While character comparison would be slightly
more efficient, using str_has_prefix() provides better readability
and maintains a uniform coding style throughout the rtla tool.
