npm: get npm package name from npm pack
Fixes [YOCTO #12534]
When using npm packages with exotic names, like "JSONSelect" (with
uppercase) or "@angular/cli" (with at sign and slash), there are three
different names:
- the recipe name ("jsonselect" or "angular-cli")
- the npm module name ("JSONSelect" or "@angular/cli")
- the npm pack name ("JSONSelect" or "angular-cli")
The commit
fa9c077068a2acea04389fa2b44eb2e93548fce2 allow to have
different recipe name and npm module name by setting the NPMPN variable.
This commit allows to have yet another npm pack name. The pack filename
is now dynamically retrieved from the 'npm pack' command.
