[PATCH] libfshelp: Fix extern inline definitions

[Romain Naour]

The commit [1] updated rlock.h and fshelp.h to use
FSHELP_DEFINE_EXTERN_INLINE but it's never defined
because FSHELP_EXTERN_INLINE is used in
libfshelp/extern-inline.c.

Update this file to use define FSHELP_DEFINE_EXTERN_INLINE.

[1] ca3d36201329f0e21b995d831ce9f6f03b6b985e

* libfshelp/extern-inline.c: define FSHELP_DEFINE_EXTERN_INLINE.
* libfshelp/fshelp.h: define FSHELP_EXTERN_INLINE __extern_inline
  if FSHELP_DEFINE_EXTERN_INLINE is not defined.
* libfshelp/rlock.h: Likewise
