[OE-core] [PATCH] perl: fix incorrect symbolic link for libperl.so

[Yi Zhao]

The perl-cross uses PERL_API_VERSION but not PERL_VERSION to define
libperl soname: libperl.so.$PERL_API_REVISION.$PERL_API_VERSION.$PERL_API_SUBVERSION.
For perl stable releases, the PERL_API_SUBVERSION is always 0. Specify
the so version for libperl to make sure the libperl.so can be linked to
the correct library.
