guix system: De-monadify bootloader installation script.

* guix/scripts/system.scm (bootloader-installer-derivation): Rename
to...
(bootloader-installer-script): ... this.  Use 'scheme-file' instead of
'gexp->file'.
(perform-action): Adjust accordingly.  Move 'lower-object' call to the
point where DRVS is computed.
