pkg_create has some code to check every @lib in a PLIST is correctly
versioned (by expanding ${LIBname_VERSION}).  This check is broken, so
the error never happens.  The broken code will cause a warning in
Perl 5.42, so we must change it before we update Perl.

When I fixed the check, it broke a few ports,

$ make -C lang/vala print-plist-all >/dev/null                        
Error: Incorrectly versioned shared library: \
@lib lib/libvala-${API_V}.so.${LIBvala-${API_V}_VERSION}

This @lib line is correct, but pkg_create looked for the exact string
'${LIBvala-0.56_VERSION}' in the unsubstituted line, and didn't find
it, because API_V=0.56 was unsubst.  There are more than 30 ports like
this; see list below diff.  (Because print-plist-all can produce the
error, I didn't need a bulk build to find the broken ports.)

I want to commit this version of the diff, which has '0 &&' to disable
the check, so ports like lang/vala don't break.  The other changes in
this diff are,
 - Change "!$x =~ m/y/" to "$x !~ m/y/", which fixes the Perl 5.42
   warning "Possible precendence problem between ! and =~".
 - Add \Q and \E to the regexp, so libestdc++ stops matching
   '${LIBestdcccccc_VERSION}'.
 - Pass the unsubstituted string to check_version: the caller did
   "my $s = $subst->do($l);", so pass $l, not $s.

In the future, we might modify and enable this check.  For example, we
might compare libvala's filename's version with LIBvala-0.56_VERSION,
without looking for '${LIBvala-0.56_VERSION}'.  This might work for
devel/libtalloc,-python which has,

@lib lib/libpytalloc-util.${PYTALLOC_UTIL_LIBSUFFIX}

We can't enable a check now, because cad/qcad has lines like,

@lib share/qcad/plugins/script/libqtscript_core.so.1.0

There is no LIBqtscript_core_VERSION=1.0; and I'm not sure whether to
add these plugins to SHARED_LIBS or change them from @lib to @so.

Is this diff with '0 &&' ok?
