bootloader: Convert device in menu-entry to proper sexp. 
Previously, menu-entry->sexp didn't try to convert `device` to a
proper sexp, which was inserted directly into the boot parameters
G-exp, leading to a G-exp input error.  Now convert both uuid and
file-system-label possibilities to sexps, and add parsing code to
sexp->menu-entry.  This fixes #57307.

* gnu/bootloader.scm (menu-entry->sexp, sexp->menu-entry): Take
non-string devices into account.
