Address a -Wformat-truncation= compiler warning.

As far as Ubuntu 18.04 kernel headers go, _UTSNAME_RELEASE_LENGTH =
= _UTSNAME_VERSION_LENGTH = _UTSNAME_MACHINE_LENGTH = _UTSNAME_LENGTH =
= 65.

char release[_UTSNAME_RELEASE_LENGTH] contains the kernel version and
possibly some suffixes, e.g. "4.15.0-29-generic". For most cases 32 bytes
should be enough.

char version[_UTSNAME_VERSION_LENGTH] contains the kernel build number,
name and date, e.g. "#31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018". This
may actually take up to 64 characters.

char machine[_UTSNAME_MACHINE_LENGTH] contains the hardware name, e.g.
"x86_64". For most cases 16 bytes should be enough.
