wolfssl: prefer regular libwolfssl over cpu-crypto
Rename libwolfssl-cpu-crypto to libwolfsslcpu-crypto so that the
regular libwolfssl version comes first when running:
opkg install libwolfssl

Normally, if the package name matches the opkg parameter, that package
is preferred.  However, for libraries, the ABI version string is
appended to the package official name, and the short name won't match.
Failing a name match, the candidate packages are sorted in alphabetical
order, and a dash will come before any number.  So in order to prefer
the original library, the dash should be removed from the alternative
library.
