[edk2-platforms][PATCH 2/2][RESEND] PlatformPayloadFeaturePkg.py: Add Linux support

["Patrick Rudolph" <patrick.rudolph@9elements.com>]

- Use OS specific path seperator instead of hardcoding ';'
- Fix case of build artifact FV/PLATFORMPAYLOAD.Fv

Test:
python Features/Intel/PlatformPayloadFeaturePkg/PlatformPayloadFeaturePkg.py
works on Linux.
