mmap()->sys_mmap2: do unsigned shift of offset
Fix the implementation of mmap based on the mmap2 system call, to
construct pgoffset from offset with an unsigned shift rather than a
signed (off_t) shift. The mmap2 test in the testsuite catches this case
by mmap'ing with a large offset (with the sign bit set). The signed
shift repeats the sign bit making the page shift way out of range. This
is already fixed similarly in mmap64().
