core: Increase the size of variable for the uevent.<hardware>.rc file name.

    The size of hardware is 32 bytes and the tmp variable should fit
    'uevent.' and '.rc' as well. In some cases like for the ST-Ericsson
    Snowball the 32 bytes were not enouth.
    hardware = "st-ericssonsnowballplatform"
