lint_fix: fix CLI arguments use

Commit df4cd065 updated how command line arguments are parsed. However,
sys.argv[0] should be ignored (as this is the name of the program).
Remove the argument, so the default value (sys.argv[1:]) is used.

Also, use the embedded_launcher so that the help renders
as:
    usage: lint_fix [-h]
instead of:
    usage: usage: __soong_entrypoint_redirector__.py [-h]

Test: lint_fix --print --no-fix --check AnnotatedAidlCounter \
       --lint-module AndroidUtilsLintChecker services.autofill
