asn1_string_to_time_t: Use timegm on FreeBSD.
FreeBSD does not provide a global timezone variable containing the
offset to UTC. Instead, FreeBSD's libc includes a legacy timezone
function dating back to Version 7 AT&T UNIX. As a result,
asn1_string_to_time_t currently fails to compile on FreeBSD as it
subtracts a function from a time_t value:
../crypto/asn1/a_time.c:625:37: error: invalid operands to binary expression ('time_t' (aka 'long') and 'char *(int, int)')
timestamp_utc = timestamp_local - timezone;
~~~~~~~~~~~~~~~ ^ ~~~~~~~~
1 error generated.
However, FreeBSD's libc does include a non-standard (but widely
available) timegm function which converts a struct tm directly to a
UTC time_t value. Use this on FreeBSD instead of mktime.
