Include PCRE2 in R 3.x on Debian 11 for Pango support

Browse source 
In Debian 11, Pango now depends on PCRE2, so R 3.x will not be compiled with
Pango support if we hide PCRE2 to prevent R 3.5 and 3.6 from taking an unnecessary
dependency on PCRE2.

To check if R 3.x was compiled without Pango support, look for this line in the
configure output:

checking whether pkg-config knows about cairo and pango... no

Or in R, check if the "bitmapType" option defaults to "Xlib" instead of "Cairo":

> getOption("bitmapType")
"Xlib"
