selinux_ima_collect_state() builds a string of the current SELinux configuration settings. The string lists each setting as a name and one digit. The length of the string therefore never changes, but is still recomputed on every call. Add selinux_ima_config_len_init() to compute the length once during selinux_init(). Update selinux_ima_collect_state() to use the stored length.
