base-files: sysupgrade: quote source image name

get_image() eval a filename without quoting it, resulting in errors with
filenames containing characters that need to be escaped.
    $ sysupgrade -T -f ./cfg\(12\).tar.gz img.bin; echo $?
    Image check 'platform_check_image' failed.
    Invalid config file. Please use only .tar.gz files
    1
    $ mv cfg\(12\).tar.gz cfg_12.tar.gz
    $ mv img\(1\).bin img.bin
    sysupgrade -T -f ./cfg_12.tar.gz img.bin; echo $?
    0

Enclose the content of $from in double quotes.
