lib: Sparc's strncpy_from_user is generic enough, move under lib/
To use this, an architecture simply needs to:
1) Provide a user_addr_max() implementation via asm/uaccess.h
2) Add "select GENERIC_STRNCPY_FROM_USER" to their arch Kcnfig
3) Remove the existing strncpy_from_user() implementation and symbol
exports their architecture had.
