Fix error check in trampoline.c

[cataphract]

The appsec helper library has a call to dlopen() during constructors that may fail. Without clearing it, a call to dlerror() after a successful call to dlsym() will return the previous error message.

man 3 dlsym() says:

The correct way to distinguish an error from a symbol whose value is NULL is to
call dlerror(3) to clear any old error conditions, then call dlsym(), and then call dlerror(3) again, saving its
return value into a variable, and check whether this saved value is not NULL.
