fix PCRE dependency for GDAL 3.2.1 and 3.3.0, don't use PCRE2

[branfosj]

(created using eb --new-pr)

While building GDAL I noticed the following in the configure log. I.e. it did not find PCRE2:

checking pcre.h usability... no
checking pcre.h presence... no
checking for pcre.h... no

This is because it looks for PCRE (pcre.h and -lpcre) and not PCRE2 (pcre2.h and -lpcre2).

With this change I see:

checking pcre.h usability... yes
checking pcre.h presence... yes
checking for pcre.h... yes
checking for pcre_compile in -lpcre... yes
