platform/x86: intel/pmt: Replace sprintf() with sysfs_emit()

Browse Source 
Replace sprintf() calls with sysfs_emit() in guid_show(), size_show(),
and offset_show() sysfs attribute handlers. The sysfs_emit() function
provides automatic buffer bounds checking and is the preferred method
for formatting sysfs output per Documentation/filesystems/sysfs.rst.

This improves safety by preventing potential buffer overflows and aligns
with current kernel coding standards for sysfs attribute implementation.
