configure: tweak nghttp2 library name fix

commit 29c7cf79e8 (shipped in 7.78.0) introduced a problem by
assuming that LIB_H2 does not have any leading whitespace.  At least
OpenBSD's native pkg-config can produce such whitespace, though:

    $ pkg-config --libs-only-l libnghttp2
     -lnghttp2

As a result, the configure check for libnghttp2 will erroneously fail.

Closes #7472
