curl: fix --local-port integer overflow

Browse source 
The tool's local port command line range parser didn't check for integer
overflows and could pass "weird" data to libcurl for this option.
libcurl however, has a strict range check for the values so it rejects
anything outside of the accepted range.

Reported-by: Brian Carpenter
Closes #3242
