set pm_macSwitch(emiMacMagpie) = 0 also for 45/NPi

[orichters]

Purpose of this PR

• when running REMIND standalone with the MAgPIE emulator, Emi|GHG|Agriculture grows if I switch on NDC carbon pricing
  
• reason: While adding 45/NPi realization, we forgot to switch off that emissions are being abated for emiMacMagpie. But in NDC, there was abatement switched off, so emissions in NDC were higher

Type of change

• Bug fix

Checklist:

• My code follows the coding etiquette
• I performed a self-review of my own code
• I explained my changes within the PR, particularly in hard-to-understand areas
• I checked that the in-code documentation is up-to-date
• gamscompile works and I'm certain all automated model tests would pass (FAIL 0 in the output of make test) if renv wasn't corrupted given the very minor code changes
• The changelog CHANGELOG.md has been updated correctly
