meson: Improve PTRACE_O_EXITKILL presence check
The PTRACE_O_EXITKILL symbol in sys/ptrace.h is an enum member, not a macro. The #ifdef check added to the GSubprocess test-case in272ec5dbca
will not detect it. Use cc.has_header_symbol() to properly detect it. According to the documentation: "Symbols here include function, variable, #define, type definition, etc.". Fixes:272ec5dbca
Closes: https://gitlab.gnome.org/GNOME/glib/-/issues/3156
