[BOLT] Use getMainExecutable() (#126698)

Browse Source 
Use LLVM's getMainExecutable() helper instead of rolling our own. This
will result in standard behavior across platforms, such as making sure
that symlinks are always resolved.

(cherry picked from commit 0abe058d7f99c9c7bbaf4ee98308c5e78d229897)
