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.
