[lldb] Resolve executables more aggressively on the host

When unifying the ResolveExecutable implementations in llvm#96256, I missed
that RemoteAwarePlatform was able to resolve executables more
aggressively. The host platform can rely on the current working
directory to make relative paths absolute and resolve things like home
directories.

This should fix command-target-create-resolve-exe.test.
