Since commit fd8171fe52b5e("target/hexagon: import lexer for idef-parser") the
hexagon target uses 'flex', 'bison' to generate idef-parser. However default
travis builder image for 'focal' may not have these pre-installed, consequently
following error is seen with travis when trying to execute the 'GCC (user)' job
that also tries to build hexagon user binary:

<snip>
export CONFIG="--disable-containers --disable-system"
<snip>
 Program flex found: NO

../target/hexagon/meson.build:179:4: ERROR: Program 'flex' not found or not
executable
<snip>

Fix this by explicitly add 'flex' and 'bison' to the list of addon apt-packages
for the 'GCC (user)' job.
