linux-boot: Add #:on-error for initrd error handling.
Suggested by Danny Milosavljevic <dannym@scratchpost.org> in <https://bugs.gnu.org/29922>. * gnu/build/linux-boot.scm (boot-system): Add #:on-error parameter and pass it to 'call-with-error-handling'. * gnu/system/linux-initrd.scm (raw-initrd): Add #:on-error and pass it. (base-initrd): Likewise.
