spl: Use binman suffix allow symbols of any SPL etype

At present we use symbols for the u-boot-spl entry, but this is not always
what we want. For example, sandbox actually jumps to a u-boot-spl-elf
entry, since sandbox executables are ELF files.

We already handle this with U-Boot by using the '-any' suffix. Add it for
SPL as well.
