scripts/Makefile.lib: EFI: Use capsule CRT instead of ESL file
The EFI Capsule ESL file (EFI Signature List File) used for authentication
is a binary generated from the EFI Capsule public key certificate. Instead
of including it in the source repo, automatically generate it from the
certificate file during the build process.
Currently, sandbox is the only device using this, so removed its ESL file
and set the (new) CONFIG_EFI_CAPSULE_CRT_FILE config to point to its public
key certificate.
