apt 0.7.14: runtime error: filename too long (tmpdir length)

when the tmpdir dir is longer than 220, there is no files saved in
tmp/sysroots/x86_64-linux/var/lib/apt/lists/ after run apt-get update,
this is because apt-get uses the path as the file name, but the file
name can't be longer than 255 according to /usr/include/linux/limits.h.

+strutl.cc: the filename can't be longer than 255
+
+The URItoFileName translates the path into the filename, but the
+filename can't be longer than 255 according to
+/usr/include/linux/limits.h.
+
+Truncate it when it is longer than 240 (leave some spaces for
+".Packages" and "._Release" suffix)
