[LTP] [PATCH] unlink09: Add _GNU_SOURCE feature macro to workaround the compile error

[Yang Xu via ltp]

In CI environment, unlink09 compiling failed on alpine/latest because loff_t
type is not declared. Add _GNU_SOURCE feature macro to enable GNU extension
to solve the problem.

For a record, this has been fixed by b4970ae94 ("lapi/fs: Replace loff_t with long long") [1]
thus closing this in patchwork as handled elsewhere.

Kind regards,
Petr
