Make HTTPSEverythwere language mapping follow the changes done with torbutton

in torbutton and soon in torlauncher we change some languages from transifex to get closer to Firefox-ESR locales.

I should find out what is the desire of the HTTPSEverywhere team regarding this, and change their files as well.

The changes are

transifex lang bn = bn-BD transifex lang en_GB = en-GB transifex lang en = en-US transifex lang es_AR = es-AR transifex lang es_CL = es-CL transifex lang es_CO = es-CO transifex lang es = es-ES transifex lang es_MX = es-MX transifex lang fy = fy-NL transifex lang ga = ga-IE transifex lang gu = gu-IN transifex lang hi = hi-IN transifex lang hy = hy-AM transifex lang ms_MY = ms transifex lang nb = nb-NO transifex lang nn = nn-NO transifex lang nl_BE = nl-BE transifex lang pa = pa-IN transifex lang pt_BR = pt-BR transifex lang pt_PT = pt-PT transifex lang si_LK = si transifex lang sv = sv-SE transifex lang zh_CN = zh-CN transifex lang zh_HK = zh-HK transifex lang zh_TW = zh-TW
