build: package: fix missing host apk dependency

build: package: fix missing host apk dependency

Currently the build with USE_APK=y fails in package/libs/toolchain:

 staging_dir/host/bin/fakeroot: line 182: staging_dir/host/bin/apk: No such file or directory
 make[2]: *** [Makefile:758: bin/targets/mediatek/filogic/packages/libgcc1-13.2.0-r4.apk] Error 127

as commit d788ab376f ("build: add APK package build capabilities") added
dependency on apk in packaging step, but there is no host build
dependency defined, thus apk binary is missing when libgcc1 apk package is being
created. So lets fix it by adding explicit apk/host dependency to all
targets in the subdirectories.
