RedfishPkg/RedfishCrtLib: Add more CRT functions

Add more functions which were missed in the first time commit,
that causes the build error with EDK2 Redfish feature driver.

strerror - We don't support this on edk2 environment.
strpbrk  - Cloned this function from edk2-LibC
File operation functions - Not supported on edk2 environment.
