kbuild: initramfs fix dependency checking for compressed target

When using initramfs compression, the data file compression suffix
gets quotes pulled in from Kconfig, e.g., initramfs_data.cpio".gz"
which make does not match a target and causes rebuild.

Fix this by filtering out quotes from the Kconfig string.

Fixes: 35e669e1a2 ("initramfs: select builtin initram compression algorithm on KConfig instead of Makefile")
