ci: build: Fix quoting of extracted commands

The build command is extracted from compile_commands.json via jq -r and
executed via $compile_cmd. The command contains shell quoting like
-DKBUILD_MODNAME='\"adrv906x_eth\"' where single quotes protect double
quotes. Replace $compile_cmd with eval "$compile_cmd" so bash properly
processes the quoting before executing Replace printf "$compile_cmd ..."
with plain string assignment compile_cmd="$compile_cmd ..." (avoids
interpreting % format specifiers)
