python3-pandas: fix stripping of build paths from generated sources

do_install failed because the glob in do_install:prepend did not match
anything, leaving sed with a literal path to a non-existent file:

  sed: can't read .../build/pandas/_libs/sparse.cpython-*/pandas/_libs/sparse.pyx.c: No such file or directory

meson names the per-target private directory <target>.so.p and puts the
generated sources directly in it, so the actual file is

  ${B}/pandas/_libs/sparse.cpython-314-x86_64-linux-gnu.so.p/sparse.pyx.c

The do_compile:append hunk was meant to do the same job for every
generated source, but it searched for ${WORKDIR}/pandas-${PV}, which no
longer exists now that sources are unpacked under ${WORKDIR}/sources, so
it silently matched nothing.

Fix the remaining pass to look for ${S} and drop the redundant (and
fragile) per-file sed in do_install:prepend. Also parenthesise the -o
expression so the name filter applies to both alternatives, and use
-print0/-0.
