upsdrvctl.exe uses incorrect path separator on Windows

[twoeater]

Description
I'm trying to run upsdrvctl.exe on a Windows system. However, the application seems to be using a forward slash (/) as a path separator instead of a backslash (\), which is the standard for Windows.

This leads to a "No such file or directory" error because the full path C:\NUT-for-Windows-x86_64-SNAPSHOT-2.8.4.443-master\mingw64\sbin/usbhid-ups.exe is invalid on Windows.

Steps to Reproduce:

1. Run the following command:

PS C:\NUT-for-Windows-x86_64-SNAPSHOT-2.8.4.443-master\mingw64\sbin> .\upsdrvctl.exe start

2. Observe the error message:

Network UPS Tools upsdrvctl.exe - UPS driver controller 2.8.4 release
Can't start C:\NUT-for-Windows-x86_64-SNAPSHOT-2.8.4.443-master\mingw64\sbin/usbhid-ups.exe: No such file or directory [지정된 파일을 찾을 수 없습니다. ]

Additional Context
I attempted to use the -r option to specify the path, but this did not resolve the issue. The application still seems to construct the path internally using the incorrect separator.

Example with -r option:

PS C:\NUT-for-Windows-x86_64-SNAPSHOT-2.8.4.443-master\mingw64\sbin> .\upsdrvctl.exe -r "C:\test\" start

The output remains the same, showing the invalid path with the forward slash:

Network UPS Tools upsdrvctl.exe - UPS driver controller 2.8.4 release
Can't start C:\NUT-for-Windows-x86_64-SNAPSHOT-2.8.4.443-master\mingw64\sbin/usbhid-ups.exe: No such file or directory [지정된 파일을 찾을 수 없습니다. ]

Windows for a couple decades supports both slashes; not sure indeed about mixing them though. Probably a platform-specific "pathsep" macro or similar trick is needed. Can you experiment and PR a solution?

Sorry just saw PR #3064.

Also, which Windows version did this happen on?

I wrote in PR.
It is be my mistake. It is not path separator issued.
Problem is usbhid-ups.exe are located in "bin", but ctl is default ref in "sbin".
but drivepath can modified ups.conf.
Sorry.

hmm, nut.exe is ref in upsdrvctl.exe's path in bin. but ctl.exe is located in sbin. can i modifying in config?
Or may i request to build this? #3065
