netatalk: Remove apfstats feature to solve dependency issues

[APCCV]

Maintainer: me / @APCCV
Compile tested: snapshot SDK ipq806x
Run tested: C2600 - snapshot. Run afpd, file sharing.

Description:
afpstats requires several libraries that would increase significantly final install size.
Eliminating from build removes dependency on GLIBC.
Fixed a typo in description define (that typo has been there for over 10 years...)

I cannot replicate the buildbot error. This thing always builds successfully.
Tried w/SDK. Tried a full snapshot image build for a C2600. Fresh git clones both, so no cached libraries. All successful.
In theory this is the only feature that is active that requires glibc. In theory if the library is not available the feature is not built.
If it is not present as an argument is assumed as true by meson build. Set is as explicitly as false. "0" doesn't work. Must be "false".
I can see an additional command line 'afpstats' utility built no matter what. There is no way to avoid it but to patch the build script. So...as I think this is enough to solve the problem, here goes a PR. It should work.
If it doesn't I can patch the script to take the additional command line utility out.
I'll bring the issue to netatalk so it can be addressed upstream.

Feature compiled as OFF as per logs from successful CI/CD tests:

Confirmed from build scripts that the afpstats feature is what pulls in the missing dependencies:

    afpd_external_deps += [
        dbus,
        gio,  
        glib,
        gobject,
    ]

Adding those four dependencies for a small utility that could eventually be used to create a netatalk status section in Luci is too much bloat.

I am confident this PR will clear the dependencies issue. Please proceed with merge.
