  proccontrol: make computeAddrWidth independent of endianness

In linux_process::computeAddrWidth(), it's trying to guess the address
size without disk access, but commit c8d7481 started opening the exe to
figure out its endianness.  This is especially a problem if a process
was attached without specifying its executable.

We can modify the auxv scan to look at *both* little-endian and big-
endian words.  If either are all zero, we know this is a 64-bit process.
We could even report which endian it is from this, although we still
wouldn't know that for 32-bit processes.

  proccontrol: improve Codegen's exe lookup

Commit c8d7481 made `Codegen::generate` start opening the executable to
determine the ABI version of the process.  However, the llproc exe isn't
always set, if the process was attached without specifying it.  We can
instead get the right path from `proc_->libraries().getExecutable()`.
