Invalid non-blank line in synaptic.desktop.in

[amaa-99]

Removed the leading '_' from the Name, GenericName and Comment entries.
(closes amaa-99#129)

This fixes the msgfmt errors:
msgfmt --desktop --template=data/synaptic.desktop.in -o synaptic.desktop -d po -v

[amaa-99]

p.s. Eventually for a separate pull:

msgfmt --desktop --template=../data/synaptic.desktop.in -o synaptic.desktop -d ../po -v --check

lists a lot of errors in the .po files:

...
../po/no.po:2080: number of format specifications in 'msgid_plural' and 'msgstr[0]' does not match
../po/no.po:2196: number of format specifications in 'msgid' and 'msgstr' does not match
msgfmt: found 10 fatal errors
../po/pa.po:7: warning: header field 'Last-Translator' still has the initial default value
../po/ps.po:7: warning: header field 'Last-Translator' still has the initial default value
../po/pt.po:7: warning: header field 'Last-Translator' still has the initial default value
../po/pt.po:1280: number of format specifications in 'msgid' and 'msgstr' does not match
msgfmt: found 1 fatal error
../po/pt_PT.po:7: warning: header field 'Last-Translator' still has the initial default value
../po/pt_PT.po:7: warning: header field 'Language' still has the initial default value
...

We could eventually enable the checks in the build file once those errors/warnings are under control, e.g.:

i18n.merge_file(
  input: 'synaptic.desktop.in',
  output: 'synaptic.desktop',
  po_dir: join_paths(meson.project_source_root(), 'po'),
  type: 'desktop',
  install: true,
  install_dir: join_paths(get_option('datadir'), 'applications'),
  args: ['-c', '-v'],
)

Thank you

What, why? The "_" prefixed lines are replaced with the translated ones by gettext. Same with the AppStream metainfo file. These are .in suffixed desktop files, you are not supposed to validate or install them directly.

@mvo5 This change should be reverted. Thanks!
