Characters between : (colon) and ; (semi-colon) gets removed in performance data output, including the colon

[johanthoren]

Issue and Steps to Reproduce

1. Create a powershell script containing:

   Write-Output "OK: All is well|'FOO'=10;4:5;6:9;"

2. Add it as an external command named check_colon.
3. Check using check_nrpe:

   # /opt/plugins/check_nrpe -s -H <IP> -c "check_colon"
   OK: All is well|'FOO'=10;4;6

Expected Behavior

I expected the output to be: OK: All is well|'FOO'=10;4:5;6:9

Actual Behavior

Instead, the colons and the number following the colons were removed. OK: All is well|'FOO'=10;4;6
