This PR changes TERMUX_PKG_RECOMMENDS entries to TERMUX_PKG_SUGGESTS where the optional dependencies in question should not be installed by default when installing that package.

Notes:

• geckodriver has TERMUX_PKG_RECOMMENDS="firefox" set meaning it will try to install it when installing geckodriver.
  firefox is in the x11 repo, which may not be installed since the geckodriver package is in the main repository channel.
  There's 3 possible solutions I see to this issue
  • 1.) Keep it as is (adding a comment in the build script pointing out the potential issue)
  • 2.) Changing the RECOMMENDS to a SUGGESTS so it doesn't default to trying to install firefox as a dependency
  • 3.) Move geckodriver to the X11 repo channel, this wouldn't be ideal either since it's only X11 dependency is non-absolute.

• glow
  I've done more of a general rewrite for this build script since it was missing its man page and shell completions.
  git is only used by glow for file discovery purposes inside Git repos, thus doesn't warrant being pulled in by it.
  If a user is using glow in a git repo, it's a fair bet they'll also have installed Git.
• qbittorrent/transmission
jackett is a rather large, optional, dependency for the BitTorrent clients and shouldn't be pulled in automatically.
• w3m
libsixel is rather non-essential to the usage of w3m
  especially with Add graphics in terminal support: - Sixel and iTerm2 protocols termux-app#2973 not yet merged.
• openssh
  while there is a sshd and ssh-agent service for openssh,
  it automatically pulling in termux-services (and by extension runit)
  may be unexpected or undesired if the user does not intend to make use of the provided services.
  The existence and method of enabling the services is already laid out in openssh's postinst script.
  And it is probably better to make opting into using termux-services a conscious decision on the user's part.
