LU-13546 pcc: exclude mmap_sanity tst8/tst9 from test list

Current RHEL8 kernel does not strictly obey POSIX syntax for
mmap() within the maping but beyond current end of the underlying
files: It does not send SIGBUS signals to the process.

For negative file offset, sanity_mmap also failed on 48 bits
ldiksfs backend on the new RHEL kernel due to too large offset:
"Value too large for defined data type".

Due to the above reasons, mmap_sanity tst8/tst9 both failed on the
new RHEL8 kernel. Thus, we execlude mmap_sanity tst8 and tst9 from
sanity-pcc and sanity test list.
