Improve linter handling of short array syntax

Browse source 
Summary: Currently, linting PHP short array syntax (i.e. `[...]`) throws an exception ("Expected open parentheses"). This diff relaxes some restrictions which prevent short array syntax from linting with `ArcanistParenthesesSpacingXHPASTLinterRule`.

Test Plan: Modified test cases.
