kconfig: streamline_config.pl: check defined(ENV variable) before using it
commit a73fbfce2cc28883f659414d598e6e60ca2214b4 upstream.
A user reported:
'Use of uninitialized value $ENV{"LMC_KEEP"} in split at
./scripts/kconfig/streamline_config.pl line 596.'
so first check that $ENV{LMC_KEEP} is defined before trying
to use it.
Fixes: c027b02d89fd ("streamline_config.pl: add LMC_KEEP to preserve some kconfigs")
