linux-user: elf: Map empty PT_LOAD segments
Some PT_LOAD segments may be completely zeroed out and their p_filesize
is zero, in that case the loader should just allocate a page that's at
least p_memsz bytes large (plus eventual alignment padding).
Calling zero_bss does this job for us, all we have to do is make sure we
don't try to mmap a zero-length page.
