Remove useless configure probe for <lz4/lz4.h>.
This seems to have been just copied-and-pasted from some otherheader checks. But our C code is entirely unprepared to supportsuch a header name, so it's only wasting cycles to look for it.If we did need to support it, some #ifdefs would be required.(A quick trawl at codesearch.debian.net finds some packages thatreference lz4/lz4.h; but they use *only* that spelling, andappear to be intending to reference their own copy rather thana system-level installation of liblz4. There's no evidence offreestanding installations that require this spelling.)Discussion:https://postgr.es/m/457962.1616362509@sss.pgh.pa.us
