cli: passing PHP_HTTP_PARSER_STRICT build option doesn't work #24697

Description

The strict-mode switch name differs between the header and the implementation, so all STRICT_CHECK() sites are compiled out.
The header logic is also inverted: passing -DPHP_HTTP_PARSER_STRICT reduces the value to 0 instead of enabling strict mode.
As a result, "strict mode" cannot be enabled by any build option.

• Request line ending with bare LF -> 200 (expected: reject)
• Header line ending with bare LF -> 200 (expected: reject)
• Blank line ending with bare LF -> 200 (expected: reject)
• HTTP/9.9 -> 200, and the response status
  line echoes "HTTP/9.9 200 OK"
• HTXP/1.1, HXXP/1.1 (protocol name typo) -> 200 (expected: reject)
• HTTP/1.1 without Host -> 200 (expected: 400)
