DO NOT MERGE: only to make CI happy

This commit set CONFIG_HUSH_PARSER_2021 as the default to trigger the CI with
this parser.

Nonetheless, the keymile (i.e. VENDOR_KM) board family is not compatible with
new 2021 hush parser.
Indeed, This boards used set_local_var() to store some variables as local shell.
They then used get_local_var() to retrieve the variables values.
Sadly, this two functions do not exist with CONFIG_HUSH_PARSER_2021.
A patch was proposed to use environment variables rather than local variables
but it does not tackle the problem, so complementary work is needed to make
this boards use CONFIG_HUSH_PARSER_2021 [1].

We also remove a #undef of CONFIG_FEATURE_SH_STANDALONE as it does not exist in
U-Boot and causes troubles in the CI.

We also set CONFIG_LTO for kirkwoord sheevaplug and phytec bk4r1, otherwise it
hits its board size limit.

We also disable some check for pylint as it was not able to find future for
commit object.
