fix(no-proxy-pattern): stop chr() corrupting IP bytes as lossy UTF-8

shirabe_php_shim::chr() returned a Rust String, which lossily
re-encodes bytes >= 0x80 as UTF-8 replacement characters. ip_get_mask,
ip_get_network, and ip_map_to_6 relied on chr() to build raw in_addr
and netmask byte arrays, corrupting IPv4-in-IPv6 mappings and CIDR
netmasks. Build the Vec<u8> byte arrays directly instead of
round-tripping through String, and un-ignore test_ip_address and
test_ip_range now that the underlying bug is fixed.

chr()'s only other caller (http_downloader.rs, an ASCII ESC byte in a
regex pattern) didn't need the indirection either, so remove the shim
function entirely.
