remove-toolchain and gotidy targets fail on test distros

[mx-psi]

Component(s)

cmd/otelcontribcol, cmd/oteltestbedcol

Describe the issue you're reporting

Since #34844 the targets that run in all components and expect a go.mod file are failing in cmd/oteltestbedcol. We should fix this!

Error is (for make gotidy):

Running target 'tidy' in module 'cmd/oteltestbedcol' as part of group 'all'
make --no-print-directory -C cmd/oteltestbedcol tidy
make[2]: *** No rule to make target 'tidy'.  Stop.
make[1]: *** [Makefile:191: cmd/oteltestbedcol] Error 2
make[1]: Leaving directory '/home/pablo.baeyens/Source/otel/opentelemetry-collector-contrib'
make: *** [Makefile:119: gotidy] Error 2
