Compile problems on FreeBSD

[Takika]

I think that FreeBSD's make uses PACKAGES as special variable. Can you change it to eg. GITEA_PACKAGES?

gitea/Makefile

Line 65 in 37bd578

PACKAGES ?= $(filter-out code.gitea.io/gitea/integrations/migration-test,$(filter-out code.gitea.io/gitea/integrations,$(shell GO111MODULE=on $(GO) list -mod=vendor ./... | grep -v /vendor/)))

We can rename it to GO_PACKAGES.
