[RP] [PATCH] Free string allocated by getline() in history_load()

[Repolho]

Note: this is another very minor leak, since it only happens once while loading
the history file, but I thought I'd throw it in as well.

history.c:history_load() calls getline(), but fails to free the string
allocated by that function.

To reproduce, simply run ratpoison with a valid ~/.ratpoison_history file,
which results in (taken from valgrind's log):

120 bytes in 1 blocks are definitely lost in loss record 125 of 193
   at 0x4C2C04B: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
   by 0x5C11A2D: getdelim (in /usr/lib/libc-2.17.so)
   by 0x41A155: history_load (history.c:195)
   by 0x41D0A2: main (main.c:720)

The attached patch fixes the issue. It was generated over the latest git,
v1.4.6-48-gb02d855.
