openssl: fix bashism in c_rehash shell script

From: André Draszik <[email protected]>

This script claims to be a /bin/sh script, but it uses a bashism:

from checkbashisms:

possible bashism in meta/recipes-connectivity/openssl/openssl/openssl-c_rehash.sh line 151 (should be 'b = a'):

	    if [ "x/" == "x$( echo ${FILE} | cut -c1 -)" ]

This causes build issues on systems that don't have /bin/sh symlinked to bash:

Updating certificates in ${WORKDIR}/rootfs/etc/ssl/certs... <builddir>/tmp/sysroots/x86_64-linux/usr/bin/c_rehash: 151: [: x/: unexpected operator
...

Fix this by using POSIX shell syntax for the comparison.
