meson: Improve PTRACE_O_EXITKILL presence check

Browse Source 
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 in
272ec5dbca 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
