varnish: use jemalloc instead of glibc's malloc on linux.

Browse source 
this is the recommanded default, as glibc cause memory leaks:

 "We ran into a problem with glibc's malloc on Linux where it seemed
 like it failed to ever give memory back to the OS, causing the system
 to swap. We have now switched to jemalloc which appears not to have
 this problem." (from varnish-cache/doc/changes.rst)
