  [ELF] --package-metadata: support %[0-9a-fA-F][0-9a-fA-F]

(This application-specific option is probably not appropriate as a
linker option (.o file offers more flexibility and decouples JSON
verification from linkers). However, the option has gained some traction
in Linux distributions, with support in GNU ld, gold, and mold.)

GNU ld has supported percent-encoded bytes and extensions like
`%[comma]` since November 2024.  mold supports just percent-encoded
bytes.  To prepare for potential adoption by Ubuntu, let's support
percent-encoded bytes.
