[Devel] [PATCH] Make new_utsname fields use the proper length constant

[Dan Smith]

The members of the new_utsname structure are defined with magic numbers
that *should* correspond to the constant __NEW_UTS_LEN+1.  Everywhere else,
code assumes this and uses the constant, so this patch makes the structure
match.
