Regression with dnf_builddep_opts option

[azeey]

1237e2f makes "dnf4" equivalent to "dnf", but the implementation skips builddep_opts

mock/mock/py/mockbuild/config.py

Lines 56 to 58 in 2fa2dbd

	for alt in ["dnf_command", "dnf_common_opts", "dnf_install_command",
	"dnf_disable_plugins", "dnf_avoid_opts"]:
	alt_opts[alt.replace("dnf", "dnf4")] = [alt]

This regression breaks build infrastructure that uses dnf_builddep_opts.

Indeed, good catch. Do you want to send a PR with fix, or shall I?
