Mark library stubs as weak

So that static linking of e.g. console.static can work.

* libdiskfs/io-stubs.c (diskfs_S_io_readsleep, diskfs_S_io_eofnotify,
diskfs_S_io_postnotify, diskfs_S_io_readnotify): Mark weak.
* libnetfs/fsstubs.c (netfs_S_file_notice_changes, netfs_S_file_getfh,
netfs_S_ifsock_getsockaddr): Likewise.
* libnetfs/fsysstubs.c (netfs_S_fsys_getfile: netfs_S_fsys_getpriv,
netfs_S_fsys_init, netfs_S_fsys_forward, netfs_S_fsys_startup):
Likewise.
* libpager/stubs.c (_pager_S_memory_object_copy,
_pager_S_memory_object_data_write,
_pager_S_memory_object_supply_completed): Likewise.
* libtrivfs/fsys-stubs.c (trivfs_S_fsys_startup, trivfs_S_fsys_getpriv,
trivfs_S_fsys_init, trivfs_S_fsys_getfile): Likewise.
* libtrivfs/io-stubs.c (trivfs_S_io_map_cntl, trivfs_S_io_get_conch,
trivfs_S_io_release_conch, trivfs_S_io_eofnotify, trivfs_S_io_prenotify,
trivfs_S_io_postnotify, trivfs_S_io_readsleep, trivfs_S_io_sigio,
trivfs_S_io_readnotify): Likewise.
