devel/lldb: fix readline/editline conflict

All three ports lldb complain about symbol size mismatching:
lldb:/usr/lib/libreadline.so.6.0: /usr/lib/libedit.so.7.0 : WARNING: symbol(emacs_meta_keymap) size mismatch, relink your program
lldb:/usr/lib/libreadline.so.6.0: /usr/lib/libedit.so.7.0 : WARNING: symbol(emacs_standard_keymap) size mismatch, relink your program
lldb:/usr/lib/libreadline.so.6.0: /usr/lib/libedit.so.7.0 : WARNING: symbol(emacs_ctlx_keymap) size mismatch, relink your program

sthen@ and others on icb diagnosed this was due to python using
base libreadline.so and llvm/lldb using base libedit.so which have
a conflicting symbol size for KEYMAP_ENTRY_ARRAY. Fix by switchig
llvm & lldb to use libreadline.so.

okay?
