Guard __libc_current_sigrtmin/max with __builtin_available
The two APIs were added for the API level 21 and beyond. Currently, its
existence is tested using the null check which is done regardless of the
min sdk version of the compilation unit. (which in turn required us to
mark the API symbol weak regardless of the min sdk version.)
Now, we have a better way of testing the API availability;
__builtin_available. The null check is replaced with the call to the
compiler-provided macro which determines if the code is running in a
version of OS where the API is known to exist.
