pcre: Depending on C++ now

Must depend on cpp for the unconditional --enable-cpp, or the build can
fail when CONFIG_PACKAGE_libpcrecpp is unset and nothing else has built
the c++ toolchain:

 configure: error: Invalid C++ compiler or C++ compiler flags
 Makefile:97: recipe for target '/usr/local/src/lede/build_dir/target-mipsel_24kc_musl/pcre-8.42/.configured_68b329da9893e34099c7d8ad5cb9c940' failed
