bits/sigset.h: Fix _EXTERN_INLINE redefinition

Commit 251a3c19cb "sleep: employ __USE_EXTERN_INLINES (with necessary fixes)"
introduces following problems:

1. __USE_EXTERN_INLINES forcibly enabled build fails

 ...
   LD libuClibc-1.0.15.so
 libc/libc_so.a(cmsg_nxthdr.os): In function `__GI___cmsg_nxthdr':
 cmsg_nxthdr.c:(.text.__GI___cmsg_nxthdr+0x0): multiple definition of `__GI___cmsg_nxthdr'
 libc/libc_so.a(close.os):close.c:(.text.__GI___cmsg_nxthdr+0x0): first defined here
 libc/libc_so.a(creat.os): In function `__GI___cmsg_nxthdr':
 creat.c:(.text.__GI___cmsg_nxthdr+0x0): multiple definition of `__GI___cmsg_nxthdr'
 libc/libc_so.a(close.os):close.c:(.text.__GI___cmsg_nxthdr+0x0): first defined here
 ...

2. libuargp wrongly contains __cmsg_nxthdr/__sigismember/__sigdelset/__sigaddset
  global symbols on platforms which includes signal.h from sys/procfs.h
  As result, static linking will fail:

  TEST_LINK argp/ bug-argp1

 /home/wbx/ppc-static/target_qemu-ppc-macppc_uclibc-ng_hard/usr/lib/libc.a(sigsetops.os):

We have to partially revert 251a3c19cb to fix problems above. It is
safe to do this after commit
 162cfaea20 *: inline constant __sig{add,del}set and __sigismember
since we are able to use new inlines from within libc and leave the
rest of world(__USE_EXTERN_INLINES) equal to glibc now.
