package/zsh: add optional support for pcre

When pcre was compiled before, zsh will use it as optional dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/bin/zsh | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libgdbm.so.4]
 0x0000000000000001 (NEEDED)             Shared library: [libpcre.so.1]
[...]
