Update zend_gdb.c

This mistyping prevents building php from source under FreeBSD

are you sure about your change tough ? the failed FreeBSD CI is related.

Note kinfo_getproc expects a process id so the kinfo_proc's ki_tracer field represents the tracing process id. I may suggest to open an issue instead describing in detail your issue (including eventually cflags and all of that) we may be able to pinpoint the root cause.

i tried to build php-7.4.33, php-8.0.29 and php-8.1.20 and it always fails:

Pls note: it's FreeBSD 9.2

Couple of things.

• the compiler proposes a fix for a supposed typo. However, does not necessarily means it s the right choice. The ki_tracep field is completely unrelated as you can see here.
• note that freebsd 9.2 is EOL since the end of 2014 and indeed at the time the ki_tracer field did not exist yet (only from FreeBSD 11). Any particular reason for not using a more recent release ?

Eventually the fix would be to disable it altogether for FreeBSD < 11 (via __FreeBSD_version__).
