The minicoredumper has multiple 2038 year problems where 'long' type
variables and strtol() function calls cause overflow on 32-bit systems
when handling timestamps after 2038-01-19.
This leads to incorrect timestamp formatting in core dump directory
names (e.g., sleep40s.20380119.031407+0000.598).
Fix by changing 'long timestamp' to 'time_t timestamp' and replacing
strtol() with strtoll() to properly handle 64-bit timestamps on
32-bit systems.
