PHP supports an initial shebang, but its comment syntax can't handle our 2-line
shebangs. So, we need to embed the 2nd-line shebang comment to look like a
PHP comment:
<?php #!/path/to/php ?>
This adds patching support to the sbang hook and support for
instrumenting php shebangs.
This also patches `phar`, which is a tool used to create php packages.
`phar` itself has to add sbangs to those packages (as phar archives
apparently contain UTF-8, as well as binary blobs), and `phar` sets a
checksum based on the contents of the package.
