[install.sh] Fixed the sed pattern to match the current image revision (#9813)

#### Why I did it
The test plan described in the `How to verify it` section caused an issue when 3 images (instead of 2) were present when executing `show boot` or `sonic-installer list` commands:
```
root@sonic:/home/admin# show boot
Current: SONiC-OS-master.0-dirty-20220118.165941
Next: SONiC-OS-master.0-dirty-20220118.165941
Available: 
SONiC-OS-master.0-dirty-20220118.165941
SONiC-OS-202012.201-a0376a6e5_Internal
SONiC-OS-202012.201-a0376a6e5_Internal_RPC
```
#### How I did it
Fixed the `sed` pattern to match the current image revision in the `install.sh` script.

#### How to verify it
Test plan:
1. Install the `imageA` by using ONIE
2. Install the `imageA-rpc` by using `sonic-installer`
3. Reboot the switch
4. Swap to the `imageA` - `sonic-installer set-default imageA`
5. Reboot the switch
6. Install  the `imageB` by using `sonic-installer`
7. Check an installed images - `show boot`
8. Reboot the switch
9. Check an installed images - `show boot`
