linuxrc: add kernel command-line argument to allow user to pass additional options to cryptsetup
Cryptsetup supports additional options like "--perf-no_read_workqueue" or
"--perf-no_write_workqueue". While it is recommended to use LUKS2 format
and make these activiation flags permanent, you can also make use of
the new kernel command-line arguments "crypt_root_options" for root device
or "crypt_swap_options" for swap device to pass additional options
to cryptsetup.
These arguments can be specified multiple times or separate multiple
options with a comma.
