Nevermind, I had general confusion on how the internals work. Here is
the update, using DEFSYM.

Subject: [PATCH] add :pass and :flags to gnutls-boot for :keylist
* lisp/net/gnutls.el (gnutls-boot-parameters): Add the keys :pass and
:flags, and update the documentation.
* src/gnutls.c (gnutls-boot): Add the keys :pass and :flags, and
update the documentation.
(syms_of_gnutls): Add the symbols :pass, :flags, and the symbols that
correspond to the enumeration constants of the GnuTLS enum
`gnutls_pkcs_encrypt_flags_t`.
(key_file2_aux): Private helper function that translates a list of
symbols to its corresponding `unsigned int` value of the GnuTLS C enum
`gnutls_pkcs_encrypt_flags_t`.
