Remove broken autocompletion overrides and restore default bash behavior

$ echo 'main(){}' >x.cpp
$ g++ x.cpp -o y.out
x.cpp:1:1: warning: ISO C++ forbids declaration of ‘main’ with no type [-Wreturn-type]

The entire completion fluff is broken (inkscape too), so remove this altogether.

For the record:

Before:

aaa_base-extras's profile.bash removed, bash-completion removed: TAB ok (standard)
aaa_base-extras's profile.bash removed, bash-completion installed: TAB ok (fancy)
aaa_base-extras's profile.bash installed, bash-completion installed: TAB ok (fancy)
aaa_base-extras's profile.bash installed, bash-completion removed: TAB broken (missing results / functions not found)

After:

[profile.bash is permanently removed; so, first two rows from above always apply]

Conclusion:

profile.bash contains garbage, and if bash-completion was installed, would paper over it and hide the issues (since loaded afterwards or something).

Yep not unterstood what complete.bash does therefore it has to be removed
