Remove markers that command PHP_CodeSniffer (Pear package base-name for
"phpcs") to skip files based on their own configuration as those files
are already with the .phpstub extension which effectively has them not
configured/already ignored by phpcs base/upstr. configuration (project
configuration file: phpcs.xml.dist)
Fix is to remove these markers/directives, also not all .phpstub files
had them therefore this is effectively streamlining the file formats
for .phpstub to this regard.
