clang-tidy: Fix absolute value calculation

Replaced the use of `abs` with `labs` for calculating the absolute value
of `timeStamp.tm_gmtoff` to resolve the `-Wabsolute-value` warning. This
ensures the correct handling of long values for timezone offsets.

'''
src/zlib_file.cpp:53:19: [0m[0;1;31m
 error: [0m[1mabsolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value [-Werror,-Wabsolute-value]

Tested: Build verified
