[PATCH v2] Fix POSIX compliance: Make blkcnt_t and blksize_t signed on alpha

[Osama Abdelkader]

POSIX requires that blkcnt_t and blksize_t are signed integer types.
On alpha, these were incorrectly defined as unsigned types (__U32_TYPE).
This change makes them signed (__S32_TYPE) to match:
- POSIX requirements
- All other architectures in glibc

Fixes #33355
