[LTP] [PATCH] utimensat: fix immutable file retcodes for 4.8.0 and newer.

[Artem Savkov]

Kernel 4.8.0 contains patch "337684a fs: return EPERM on immutable inode" that
makes operations on immutable files return EPERM instead of EACCESS.

Adjust utimensat test to check new retcode for kernels 4.8.0 and newer.
