Subject: *.pc.in: add lib prefix to lib names w/MSVC

this fixes the library names output after:
9ac25bcb3 CMakeLists.txt,win32: match naming convention used by nmake

before this change:
pkg-config --libs --msvc-syntax \
  libwebp libwebpdemux libwebpmux libsharpyuv libwebpdecoder
/libpath:.../lib webpdemux.lib webpmux.lib webp.lib
  sharpyuv.lib webpdecoder.lib

after:
pkg-config --libs --msvc-syntax \
  libwebp libwebpdemux libwebpmux libsharpyuv libwebpdecoder
/libpath:.../lib libwebpdemux.lib libwebpmux.lib libwebp.lib
  libsharpyuv.lib libwebpdecoder.lib

Bug: webp:584
Change-Id: Ic3693b58a40e0ba683333065003b1c00aab0cf48
