Title: libzzip 0.13.60 & fix link error with clang

Upgrade libzzip to 0.13.60.
Fix a link error with clang & libtool. Configure chooses
--export-dynamic
but that flag doesn't normally start with two dashes, only one.
There are no overrides or switches available for that.
The fix is an inline patch for configure, adding the compiler case
for darwin*) to set ZZIPLIB_LDFLAGS="-export-dynamic".
Add the inline patch and bug report url to the formula.
Add the 2sec make check for this compression library.
Checks on Lion 10.7.3 and SL 10.6.8 with all five compilers from
the 4.3 CLT and XCode-4.0.2 (4D502).
