sci-libs/pgplot: update HOMEPAGE to sites.astro.caltech.edu

The www.astro.caltech.edu/~tjp/pgplot/ host now permanently redirects
to sites.astro.caltech.edu (caltech IT migration). Point HOMEPAGE at
the new canonical location so pkgcheck stops flagging RedirectedUrl.

sci-libs/pgplot: fork ::gentoo-r9 as -r99 with -std=gnu89 fix

::gentoo's sci-libs/pgplot-5.2.2-r9 builds with the C compiler default, which on gcc
16 (-std=gnu23) rejects K&R-style prototypes in drivers/figdisp_comm.c (e.g. 'void
figdisp_convbufout();' followed by two-arg calls). Fork the ebuild as -r99 and add
'append-cflags -std=gnu89' in src_configure so K&R survives. Patches and Manifest
DIST hash match ::gentoo verbatim. Drop this fork once ::gentoo lands an equivalent
fix.
