fix CBA_fnc_compatibleMagazines skipping muzzle magazines

[commy2]

When merged this pull request will:

• CBA_fnc_compatibleMagazines ignores sub muzzle magazines and magwells
• Therefore arifle_mx_F and arifle_mx_GL_F are claimed to use the same mags even though GL is compatible with all the under barrel grenade launcher rounds

Before:

"arifle_MX_GL_F" call CBA_fnc_compatibleMagazines
//["30Rnd_65x39_caseless_mag","30Rnd_65x39_caseless_mag_Tracer","30Rnd_65x39_caseless_green","30Rnd_65x39_caseless_green_mag_Tracer"]

"Throw" call CBA_fnc_compatibleMagazines
[]

After:

"arifle_MX_GL_F" call CBA_fnc_compatibleMagazines
//["30Rnd_65x39_caseless_mag","30Rnd_65x39_caseless_mag_Tracer","30Rnd_65x39_caseless_green","30Rnd_65x39_caseless_green_mag_Tracer","1Rnd_HE_Grenade_shell","UGL_FlareWhite_F","UGL_FlareGreen_F","UGL_FlareRed_F","UGL_FlareYellow_F","UGL_FlareCIR_F","1Rnd_Smoke_Grenade_shell","1Rnd_SmokeRed_Grenade_shell","1Rnd_SmokeGreen_Grenade_shell","1Rnd_SmokeYellow_Grenade_shell","1Rnd_SmokePurple_Grenade_shell","1Rnd_SmokeBlue_Grenade_shell","1Rnd_SmokeOrange_Grenade_shell","3Rnd_HE_Grenade_shell","3Rnd_UGL_FlareWhite_F","3Rnd_UGL_FlareGreen_F","3Rnd_UGL_FlareRed_F","3Rnd_UGL_FlareYellow_F","3Rnd_UGL_FlareCIR_F","3Rnd_Smoke_Grenade_shell","3Rnd_SmokeRed_Grenade_shell","3Rnd_SmokeGreen_Grenade_shell","3Rnd_SmokeYellow_Grenade_shell","3Rnd_SmokePurple_Grenade_shell","3Rnd_SmokeBlue_Grenade_shell","3Rnd_SmokeOrange_Grenade_shell"]

It was designed to work for specific muzzles (that's why it takes a config)
This changes break code I've written,

_weapon = "CUP_launch_Mk153Mod0";
{
    if (_x == "this") then { // main gun magazines
        [LAW_PRIMARY_MUZZLE_MAG_INDEX, [configFile >> "CfgWeapons" >> _weapon] call CBA_fnc_compatibleMagazines]
    } else { // underslung weapon magazines
        [LAW_SECONDARY_MUZZLE_MAG_INDEX, [configFile >> "CfgWeapons" >> _weapon >> _x] call CBA_fnc_compatibleMagazines]
    } params ["_arrayIndex", "_magazines"];
    
    // set mag in arrayIndex...
} forEach getArray (configFile >> "CfgWeapons" >> _weapon >> "muzzles");
