imagebuilder: clean KDIR_TMP before building
Building images usally stores them in KDIR_TMP and then copies them over to BIN_DIR. This is fine as rebuilding of images overwrites existing images. When using the EXTRA_IMAGE_NAME variable frequently this fills up the ImageBuilder KDIR_TMP folder since every built image is stored forever. This commit clears the KDIR_TMP folder before building a new image. Below an example how sysupgrade.openwrt.org filled up after the release of 22.03.0 where every created image contains a hash of the package selction in the filename: aparcar@asu-01:~/asu/worker1/cache/22.03.0$ du -d 1 -h 400M ./kirkwood 260M ./gemini 2.0G ./ipq806x 1.7G ./ipq40xx 8.1G ./ramips 4.0K ./octeon 495M ./sunxi 728M ./lantiq 1.8G ./rockchip 3.7G ./mediatek 4.0K ./realtek 5.4G ./mvebu 8.9G ./ath79 3.0G ./bcm47xx 14G ./bcm27xx 11G ./x86 4.0K ./bcm63xx 312M ./mpc85xx 600M ./apm821xx 5.4G ./bcm53xx 66G .
