File ptpd-evp-md-ctx.patch of Package ptpd

Subject: [PATCH] ntp_isc_md5: rename EVP_MD_CTX into PTPD_EVP_MD_CTX

EVP_MD_CTX can conflict with openssl that defines a completely different
typedef with same name.

Since this typedef is used only twice in the entire ptpd,
substitute EVP_MD_CTX with PTPD_EVP_MD_CTX.
