    set_locale should call tzset. (Closes: #848249)
    
    This is necessary to update timezone information for C code we've pulled in
    that might've already called it.  In particular, the python-magic libmagic
    wrapper can be affected by this, and print out gzip mtimes in the user's
    timezone.
