pkg/usrlocalsharelima: add a candidate directory to searching lima-guestagent

When debugging `cmd/limactl` with `dlv dap`, the executable appears as follows:
`cmd/limactl/__debug_bin2611107549`.
In this case, `limactl` fails to locate `lima-guestagent` relative to the expected executable path and results in the following error:
```json
{
  "level": "fatal",
  "msg": "failed to find \"lima-guestagent.Linux-aarch64\" binary for \"/Users/norio/ghq/github.com/lima-vm/lima/cmd/limactl/__debug_bin2611107549\", attempted [/Users/norio/ghq/github.com/lima-vm/lima/cmd/limactl/lima-guestagent.Linux-aarch64 /Users/norio/ghq/github.com/lima-vm/lima/cmd/share/lima/lima-guestagent.Linux-aarch64]",
  "time": "2024-09-24T15:02:23+09:00"
}
```
To avoid this error, it was necessary to create a symbolic link (`ln -sf ../_output/share cmd/share`) so that `lima-guestagent*` exists at the expected relative path.
This change adds `_output/share/lima/lima-guestagent.*` to the search directories, making the symbolic link creation unnecessary before running `dlv dap` for debugging.
