Add READ access of mmap() in docker env

In docker multi-architecture environment, calling the
mmap() with only PROT_WRITE would fail the following
write(). Adding PROT_READ access would solve the issue.
The logic there only needs WRITE access, however, it
should be fine to assign READ access too. Actually,
PROT_WRITE is offen implementated as PROT_READ|PROT_WRITE.

fix: #7135.
