[PATCH 1/1] Makefile: make clean should delete include/generated/env.in

[Heinrich Schuchardt]

'make sifive_unamtched_defconfig; make clean; make' fails if file
include/generated/env.in exists. 'make clean' should remove all files that
stop building.

Add file include/generated/env.in to the clean target.
