Andreas Kling d6af3302e8 LibELF: Don't recompute the same ELF hashes over and over ...

When performing a global symbol lookup, we were recomputing the symbol
hashes once for every dynamic object searched. The hash function was
at the very top of a profile (15%) of program startup.

With this change, the hash function is no longer visible among the top
stacks in the profile. :^)
