gen_initramfs_list.sh: fix 'bad variable name' error
Prior to commit 858805b336be ("kbuild: add $(BASH) to run scripts with
bash-extension"), this shell script was almost always run by bash since
bash is usually installed on the system by default.
Now, this script is run by sh, which might be a symlink to dash. On such
distributions, the following code emits an error:
local dev=`LC_ALL=C ls -l "${location}"`
You can reproduce the build error, for example by setting
CONFIG_INITRAMFS_SOURCE="/dev".
GEN usr/initramfs_data.cpio.gz
./usr/gen_initramfs_list.sh: 131: local: 1: bad variable name
make[1]: *** [usr/Makefile:61: usr/initramfs_data.cpio.gz] Error 2
This is because `LC_ALL=C ls -l "${location}"` contains spaces.
Surrounding it with double-quotes fixes the error.
Fixes: 858805b336be ("kbuild: add $(BASH) to run scripts with bash-extension")
