simplify Perl_xs_apiversion_bootcheck
We control both strings. Perl API versions are not old decimal or alphas
versions. Maints dont increase Perl API ver. Just do a memcmp. Faster and
less machine code. Before 0xA6 bytes of machine code on VC 2003 32b,
after 0x35. This patch is related to [perl #123136].
