sepolicy: qcom: Don't audit hal_gnss_qti reading xtra-daemon control property

Silences the following SELinux denial:

[   13.227324] type=1400 audit(1696156342.168:13): avc: denied { read } for comm="Loc_hal_worker" name="u:object_r:xtra_control_prop:s0" dev="tmpfs" ino=15652 scontext=u:r:hal_gnss_qti:s0 tcontext=u:object_r:xtra_control_prop:s0 tclass=file permissive=0

Reason for silence instead of allow: Refer to comments on https://review.lineageos.org/c/LineageOS/android_device_lineage_sepolicy/+/367498
