build: Move rm command in installation.

Should fix these opkg errors:

     * check_data_file_clashes: Package tzdata-etcetera wants to install file /usr/share/zoneinfo/Etc/Zulu
            But that file is already provided by package  * tzdata
     * check_data_file_clashes: Package tzdata-etcetera wants to install file /usr/share/zoneinfo/Etc/Universal
            But that file is already provided by package  * tzdata
     * opkg_install_cmd: Cannot install package tzdata-etcetera.
