[PATCH v3] Fix POSIX compliance: Make blkcnt_t and blksize_t signed on alpha

POSIX requires that blkcnt_t and blksize_t are signed integer types.
On alpha, these were incorrectly defined as unsigned types.
This change makes them signed to match:
- POSIX requirements
- All other architectures in glibc

Fixes #33355
