libbb: code shrink and speed up index_in_strings()
Rewrite index_in_strings() to replace calls to strcmp()/strlen().
With this change searching for valid names in the applet_names
array (for example) is 40% faster.
The code has to assume the strings aren't sorted, so will always scan
the entire array when presented with an invalid name.

index_in_strings 63 56 -7
