@pcre2: fix broken symbol versioning test in configure

Recursive bump will likely be needed.

Fix missing symbol versioning:

Don't let CONFIGURE_ENV override libtool's internal CP/MV/RM.
pkgsrc exports RM as "/bin/rm" but these tests really need "rm -f" because
of how they are written.

When creating a soname symlink the generated libtool runs
$RM "$linkname" && $LN_S "$realname" "$linkname"
which fails because $linkname does not exist yet.

PCRE2_CHECK_VSCRIPT links a shared library to probe for
-Wl,--version-script and the probe fails due to rm without -f even though
the link itself succeeded. Symbol versioning is then silently dropped and
configure says "with symbol versioning : n/a" rather than "yes".

The root cause is in libtool and a similar issue was reported
upstream in 2010:
