package/audit: Fix type output on log folder creation

Testing buildroot 2021.05 I observed that after first
boot I was having the following folders:

/context:
/system_u:object_r:auditd_log_t

The root of this problem turned to be a difference in the
output of $(selabel_lookup -b file -k /var/log/audit) called
by S02auditd that from this version on looks like:

$ selabel_lookup -b file -k /var/log/audit
Default context: system_u:object_r:auditd_log_t

This patch will cut it to retrieve the type piece only. Unfortunately,
audit has no options to create machine-readable output that is
guaranteed not to change, so that's the best we can do.
