pcp: Add readline-native and ncurses-native to pcp-native DEPENDS

pcp-native compiles the pcp sources src/pmns/lex.l which does
'#include <readline/readline.h>'. The native recipe only depended on
python3/setuptools/flex/bison, so with the header search correctly
limited to the sysroot
0001-configure-Limit-the-header-search-to-sysroot.patch
the build fails on hosts without readline development headers installed:

    lex.l:25:10: fatal error: readline/readline.h: No such file or directory

Depend on readline-native (and ncurses-native, which readline links
against) so the headers and libraries come from the native sysroot
rather than the build host, mirroring the target recipe DEPENDS. This
makes the native build reproducible and host independent.

Verified by building pcp-native from scratch
