MozNSS: load certificates from certdb, fallback to PEM
If TLS_CACERT pointed to a PEM file and TLS_CACERTDIR was set to NSS certificate database, the backend assumed that
the certificate is always located in the certificate database. This assumption might be wrong. This patch makes the
library to try to load the certificate from NSS database and fallback to PEM file if unsuccessfull.
