getLongLongFromObject: use string2ll() instead of strict_strtoll().

Browse Source 
strict_strtoll() has a bug that reports the empty string as ok and
parses it as zero.

Apparently nobody ever replaced this old call with the faster/saner
string2ll() which is used otherwise in the rest of the Redis core.

This commit close #3333.
