uip/sortm.c: Remove unused variable and dlocaltimenow() call.

read_hdrs() has a auto `struct tws tb'.  It's only use is as the
destination for dlocaltimenow()'s result.  Remove the variable.  Also
remove the dlocaltimenow() call;  this I'm unsure about as it has a side
effect of calling tzset(3).  However, tests pass.  Repository history
sheds no light.
