Revert to commits as they broke few rump tests

"Include namespace.h in a few of libc source files
[...]
    This change finishes elimination of usage of the global name of the
    following symbols:
      - close -> _close
      - execve -> _execve
      - fcntl -> _fcntl
      - setcontext -> _setcontext
      - wait6 -> _wait6
      - write -> _write
      - writev -> _writev"

"Register more syscalls in namespace.h (of libc)

    Add weak symbols for:
     - fcntl
     - close
     - execve
     - setcontext
     - wait6
     - write
     - writev"

These changes broke:

    fs/nfs/t_rquotad:get_nfs_be_1_both
    fs/nfs/t_rquotad:get_nfs_be_1_group
    fs/nfs/t_rquotad:get_nfs_be_1_user
    fs/nfs/t_rquotad:get_nfs_le_1_both
    fs/nfs/t_rquotad:get_nfs_le_1_group
    fs/nfs/t_rquotad:get_nfs_le_1_user
    lib/librumphijack/t_config:fdoff
    lib/librumphijack/t_tcpip:http
    lib/librumphijack/t_tcpip:nfs
    lib/librumphijack/t_vfs:cpcopy
    lib/librumphijack/t_vfs:mv_x
    lib/librumphijack/t_vfs:paxcopy
    net/net/t_forwarding:ipforwarding_fastforward_v4
    net/net/t_forwarding:ipforwarding_fastforward_v6
    net/net/t_forwarding:ipforwarding_fragment_v4
    net/net/t_forwarding:ipforwarding_misc
    net/net/t_mtudisc6:mtudisc6_basic

This revert fixes the failures, except lib/librumphijack/t_vfs.

The original changes were added in order to facilitate a usage of
sanitizers against programs linked with NetBSD's libc. It is no longer
needed, so abandon these changes.
