[libc] Change fsfilcnt_t and fsblkcnt_t to be 64-bits long

[mikhailramalho]

In 32-bit systems with 64-bit offsets, both fsfilcnt_t and fsblkcnt_t are 64-bit long, just like 64-bit systems. This patch changes both types to be 64-bit long for all platforms and follows the reasoning used to change off_t: the standard only requires it to be an unsigned int, so making it 64-bit long doesn't violate this property.

It should be NFC for 64-bit systems.
