Subject: [PATCH] src/t_stripealign.c: Fix complier error

The FIEMAP_EXTENT_SHARED flag was added into kernel since commit
8c0414cd524e, so undefined FIEMAP_EXTENT_SHARED resulted in complier
error on old distros(e.g. RHEL6), as below:
----------------------------------------------------------------------
t_stripealign.c:99: error: 'FIEMAP_EXTENT_SHARED' undeclared (first use in this function)
----------------------------------------------------------------------

We fix it by defining the flag manually.
