I'm still seeing gotwebd increasing its memory usage over time so I'm
still searching for leaks.

I've seen that we miss two free on the string returned by
gotweb_get_time_str, and while here I'm also dropping a redundant
ternary operator (age cannot be NULL if gotweb_get_time_str returned
successfully.)

this still doesn't explain why gotwebd reached 600M of RES in hours,
so there's probably more.

ok?
