vendor.sh: don't load entire coreboot configs
instead, only grep for the entries required, such as Intel ME paths. some variables in coreboot configs use $(), which is used in *make*, on the coreboot build system, and there refers to variables. here, we are sourcing them from sh, which treats this as a mini subshell to run a command; for example CONFIG_FOO would be executed, which is bad. The current logic still theoretically has this problem, with this patch, but the entries we scan from the configs do not currently have variable names in the strings. So: filter out just what we need, into a temporary config, when scanning for vendor files in coreboot configs, and use the temporary config. This fixes a build error when compiling for e5520_6mb.
