Subject[RFC 06/32] isofs: fix timestamps beyond 2027
Date
isofs uses a 'char' variable to load the number of years since
1900 for an inode timestamp. On architectures that use a signed
char type by default, this results in an invalid date for
anything beyond 2027.

This adds a cast to 'u8' for the year number, which should extend
the shelf life of the file system until 2155.
