elf: Pass the fd to note processing

Browse Source 
To handle GNU property notes on aarch64 some segments need to
be mmaped again, so the fd of the loaded ELF module is needed.

When the fd is not available (kernel loaded modules), then -1
is passed.

The fd is passed to both _dl_process_pt_gnu_property and
_dl_process_pt_note for consistency. Target specific note
processing functions are updated accordingly.
