fs/fuse kio: convert _inline_buffer[0] to flexible array member
Zero-length arrays cause FORTIFY_SOURCE __write_overflow_field warnings
on every memcpy into _inline_buffer, because __builtin_object_size
returns 0 for [0] arrays. Converting to C99 flexible array members ([])
makes the size "unknown" to the compiler, silencing the false positives
in pcs_sock_io.c, pcs_rpc.c, pcs_cs.c and pcs_krpc.c.
Fixes: 923a394f288cc ("fuse kio: Add pcs engine combo v0.8")
