u* tools: PHP support

Introduce PHP support to ucalls, uflow, and ustat. The PHP probes
used are for function entry and exit, file compile (~ class load),
and exception throw. This requires a PHP runtime built with the
`--enable-dtrace` configure switch. Some probes also require
USE_ZEND_DTRACE=1.

Resolves #945.
