[yocto] [meta-selinux][sumo][PATCH 4/7] libpcre_selinux.inc: fix do_install failure if .so file does not exist

[Joe MacDonald]

From: Chen Qi <Qi.Chen at windriver.com>

In case of the existence of meta-mingw, the library is .dll instead of
.so and these .dll files are in ${bindir}.

We need to check the existence of the .so file before doing readlink,
otherwise do_install fails.
