perl: fix installation failure because of shell issue

On one of my buildservers I noticed perl do_install failing with the
following message:

| rm: cannot remove '<OEROOT>/tmp-rpb-glibc/work/armv8-2a-linaro-linux/perl/5.32.0-r0/image//usr/lib/perl5/5.32.0/*/CORE/libperl.so': No such file or directory

I tracked this down to shell being dash rather than bash not being able
to expand this glob in the middle of the filename. So replace the glob
expansion with the simpler one which works in all cases.
