Peter A. Bigot fd903cda43 go-mod.bbclass: use append to add modcacherw
This class provided default build flags but includes the base go class
which also provides default flags.  Use a different mechanism to
extend the default flags without discarding `-trimpath` from the base
class.

# Handle Go Modules support
#
# When using Go Modules, the the current working directory MUST be at or below
# the location of the 'go.mod' file when the go tool is used, and there is no
# way to tell it to look elsewhere. It will automatically look upwards for the
# file, but not downwards.
#
# To support this use case, we provide the `GO_WORKDIR` variable, which defaults
# to `GO_IMPORT` but allows for easy override.
#
# Copyright 2020 (C) O.S. Systems Software LTDA.
# The '-modcacherw' option ensures we have write access to the cached objects so
# we avoid errors during clean task as well as when removing the TMPDIR.
