libedit: fix build error with musl toolchain

Browse Source 
Libedit build fails when __STDC_ISO_10646__ is not defined, and that is
the case when compiling with musl toolchains.

chartype.h:52:3: error: #error wchar_t must store ISO 10646 characters
  #error wchar_t must store ISO 10646 characters
   ^

Musl is ISO 10646 compliant but doesn't define __STDC_ISO_10646__, so
let's define it manually.
