allow apexd to mount apex-info-list.xml file
apexd runs in two separate mount namespaces: bootstrap & default.
To support separate apex-info-list.xml for each mount namespaces, apexd
needs to emit separate .xml file according to the mount namespace and
then bind-mount it to apex-info-list.xml file.
Bug: 158964569
Test: m & boot
nsenter -m/proc/1/ns/mnt -- ls -lZ /apex/apex-info-list.xml
nsenter -m/proc/2/ns/mnt -- ls -lZ /apex/apex-info-list.xml
=> shows the label apex_info_file correctly
