locks: use once execution for on-demand initialization of globals
This makes sure that the global variables are initialized only once.
Most of those variables are initialized at ELF constructor, though a
couple of occasions they are initialized on-demand: the global keylog
file pointer and TPM2 TCTI context. To properly protect the
initialization this patch uses gl_once provided by Gnulib.
