  [lit] Normalize RLIM_INFINITY to "infinity" in print_limits.py for Python 3.15+ (#190953)

Python 3.15 changed resource.getrlimit() to return the platform's
maximum value (e.g., 18446744073709551615 on 64-bit systems) instead of
-1 for RLIM_INFINITY. This breaks lit tests that expect -1 for unlimited
resource limits.

This patch normalizes the return value to "infinity" when it equals
RLIM_INFINITY to maintain compatibility with existing tests across all
Python versions.

Fixes test failure: shtest-ulimit-nondarwin.py
Expected: RLIMIT_FSIZE=-1
Got: RLIMIT_FSIZE=18446744073709551615
