bootconfig: do not put quotes on cmdline items unless necessary
When trying to migrate to using bootconfig to embed the kernel's and
PID1's command line with the kernel image itself, and so allowing
changing that without modifying the bootloader, I noticed that
/proc/cmdline changed from e.g.
console=ttymxc0,115200n8 cma=128M quiet -- --log-level=notice
to
console="ttymxc0,115200n8" cma="128M" quiet -- --log-level="notice"
The kernel parameters are parsed just fine, and the quotes are indeed
stripped from the actual argv[] given to PID1. However, the quoting
doesn't really serve any purpose and looks excessive, and might
confuse some (naive) userspace tool trying to parse /proc/cmdline. So
do not quote the value unless it contains whitespace.
