[E-devel] TGA loader crashes with corrupt RLE targa files

[Matias G. <mdh...@gm...>]

Hello,

We encountered a crash in imlib2 when loading corrupt RLE .tga files,
and this patch fixes it. The remaining buffer space could also be
checked a bit higher, to see if there's enough room for all raw packet
samples requested, but I simply chose to grab as many valid samples as
possible instead.
