package/sconeserver: re-add dependency to pcre

While pcre was an optional dependency with autoconf [1] upstream removed
the HAVE_LIBPCRE defines with the introduction of cmake [2] breaking the
build without pcre after buildroot switched to cmake with commit
8b42bbf30a914b0fd40a4518e61ac7bc511a7deb.
