imagebuilder: copy from buildroot only target/linux/generic and target/linux/<target> to reduce the size

Browse Source 
This reduces the size of a single imagebuilder by about 40MB
In example for the target ath79 it would be the sum of generic and <target> directories, so about 16MB,
instead of the whole size of the target directory, about 53MB:
11M	target/linux/generic/
3.9M	target/linux/ath79/
