[bug#70256] [PATCH v2] gnu: signon-plugin-oauth2: Fix installing in a doubled prefix.

[Sughosha]

This commit fixes creating one more /gnu/store/ directory inside its
own prefix, creating again the same prefix inside it and then
installing in it.

* gnu/packages/qt.scm (signon-plugin-oauth2)[arguments]:
<#:make-flags>: Remove argument.
<#:phases>: In configure phase, add SIGNON_PLUGINS_DIR variable.
