checkAPIs: use new regex to remove comments.

The new pattern is from the Perl FAQ; it works better for me than the
old code.  Of note is that it works with C++/C99-style comments
following a statement (as opposed to at the start of a line).

The new regex is only slightly slower than the old one: `make checkAPI`
goes from 3m30s of user time to 3m35s.

The big functional difference can be seen by looking at the
post-removal contents of packet-hl7.c.

Before:

    struct msh {                    // typical/default values
        char field_separator;       //
        char component_separator;   //
        char repetition_separator;  //
        char escape_character;      // &\0\0MSH\0\0';
                    if (tree) {

(With the old regex we lost a lot of code!)

After:

    struct msh {
        char field_separator;
        char component_separator;
        char repetition_separator;
        char escape_character;
        char subcomponent_separator;
        char message_type[4];
        char trigger_event[4];
    };
