Update build.ps1

[Fishy78]

Due windows system rights it is not allowed for a non-elevated user to create or change the KeePassConfiguration.xml due it is located at "C:\Program Files\WindowsPowerShell\Modules\PoShKeePass\2.1.3.0".
The proposed extension checks the right to write the configuration and creates, if necessary, a new empty configuration file either at $PSScriptRoot or in %AppData%\PoShKeePass.
Advantage:

• In any case the module finds a fully working configuration file
• Any user can use his own KeePass Containers
  Neutral:
• There is usually no global configuration file except for elevated Administrators
  Disadvantage:
• Is the script is used e.g. in a scheduled task, the "executing" user needs to have writing rights to the configuration. Maybe it is necessary to add a switch to override the write check.
