Add sepolicy for RamdumpService to access property sys.boot.reason on B1C1

Denied pattern is:
avc: denied { read } for name="u:object_r:system_boot_reason_prop:s0" dev="tmpfs" ino=21223 scontext=u:r:ramdump_app:s0:c206,c256,c512,c768 tcontext=u:object_r:system_boot_reason_prop:s0 tclass=file permissive=0

Bug: 132220248

Test: Manually, local run pass. RamdumpService can access the property.
