Reproducer for strftime leak

Several functions like strftime allocate memory on the first use which is not
cleaned up on shutdown by default. heaptrack reports such allocations as memory
leaks.

glibc provides a cleanup method which can be used to release this memory before
exit, see, for example, valgrind documentation.

Attached is a reproducer.

 $ g++ leak-strftime.cpp
 $ ./a.out
 $ heaptrack ./a.out
heaptrack output will be written to
"/home/centos/work/heaptrack-eval/heaptrack.a.out.16784.gz"
starting application, this might take some time...
heaptrack stats:
        allocations:            4
        leaked allocations:     3
        temporary allocations:  0
Heaptrack finished! Now run the following to investigate the data:

  heaptrack_print "/home/centos/work/heaptrack-eval/heaptrack.a.out.16784.gz" |
less
 $ heaptrack ./a.out noleak
heaptrack output will be written to
"/home/centos/work/heaptrack-eval/heaptrack.a.out.16809.gz"
starting application, this might take some time...
heaptrack stats:
        allocations:            4
        leaked allocations:     0
        temporary allocations:  1
