Escape `+` characters in rule names

When adding an `action()` in buildtools/third_party/libc++/BUILD.gn,
we get

    ninja: error: toolchain.ninja:629: expected newline, got lexing error
    rule __buildtools_third_party_libc++_write_libcxx_modulemap___build_tool...
                                      ^ near here

without this.
