linux/hardened/5.19: fix build

Browse source 
The options GCC_PLUGIN_RANDSTRUCT{,_PERFORMANCE} have been renamed to
`RANDSTRUCT_*` in 595b893e2087de306d0781795fb8ec47873596a6 since CLang
is about to support this as well and thus the options had to be
generalized.

Also, the file that is used to generate the seed has changed, only the
reference to the file in the patch was changed on adding Linux 5.19[1]
